Unimog U1550 Expedition Truck — New Shelter Buildup

New Shelter Buildup

The mounting of my rear storage boxes is described under Unimog Truck Rework. In this section, everything starts with the installation of my windows. A friend told me about a new company, who builds genuine glass windows similar to KCT. But they are way cheaper. After an extensive and excellent counseling interview by the owner I order these windows in spring 2022. The shipment is planned for June, which will fit my time planning perfectly. End of June I receive the message that my windows will be shipped next week, which will be the first week of July. This still fits my plan, because there was also a major delay with the lift of my drivers cabin — the original two weeks turned out to be two months…

One week after(!) the promised delivery date I receive the message, that there has been one window less shipped — it will now take another 3 weeks until they are able to ship my windows — which turns out to be 7 weeks. Really great that they sent the final bill already with the first shipment announcement in June and I payed immediately…

When the windows eventually arrive by the end of August, the shim strips and the line strips for the outside are missing. After a longer phone call with the owner I must learn, that I don’t need the shim strips (great that they are also payed!). He wants to ship the line strips next week. That is still okay, because I can start working on the window cutouts. For this task I receive again very valuable hints and advice from the company owner.

For the installation I must do two different cutouts: A smaller one for the outside and a bigger one for the inside. I have drawn them both already on the walls while waiting for the windows. Because I don’t have an immersion saw I try it with my jigsaw. For this I drill the appropriate holes in the corners. This works even better than expected. But despite all caution the jigsaw saw blade start to warp to the outside. But for this to cover I have my line strips. For the cutout on the inside I use my Multimaster with the big half circular saw, because I am only allowed to cut down to the wood on the outer side and not further. Therefore I adjust the depth accordingly. Also this works pretty well and I receive a nice cutout. Anyways, the pulse really increases if you start to cut these big holes in your shelter, which has the price of a compact car…

Because my shelter has an additional layer of wood behind the layer of plastic, I think about how to protect the cutting edge. First I think about placing a glass–fiber epoxy layer to seal everything in case some water should ingress. But thinking twice, this is rather too much. All in all the wood will not swell while being submerged in water, what I tested. Therefore I think it will be sufficient to paint everything just with my wood stain. I also paint the isolating foam to close the upper pores. This should be enough preparation work for the installation.

The window can be removed from the frame during installation. Only the hinge stays in the frame. Then the compression tape will be placed in the frame and the two lines of glue for the inside and outside walls. Sure I have cleaned and degreased everything before very thoroughly. Then I press the window in the cutout and adjust it. Finally I fix it in place with screw clamps and pieces of wood. I am really curious how this will look like once it is finished…

In the meantime I try to eventually receive my line strips by emails and calls. But he fobs me from week to week. Slowly it is getting really tight, because I have inspection in October and I urgently need a service appointment for my truck before that. But everything is in vain and I don’t receive the strips! Although this would be just 2h of work for him and all the calls and emails have surely eaten up more time already. When I was starting to get extremely upset about him, he is willing to ship the line strips — but he had to realize that he ordered not enough material. Therefore I only have strips for two windows now. When I unpack them I must realize that on two strips part of the corner is missing. He had cut them too short!

I immediately complain about this and receive the promise that he will definitely ship new ones with the rest. I am just wondering, when this will happen. All in all I must now cancel all appointments and hope that I will receive the strips at least in time before it is getting too cold for glueing.

So I am only able to finish one window. But at least I want to finish this one, before it is getting really cold. Most of the work is really the precise masking in order to be able to place a nice surrounding glue cover to the outside and to the window. When I remove the masking tape it is getting really thrilling — and it looks pretty good!

After everything is hardened through, I am able to mount the window back in the frame. Two friends of mine help me here, because it is impossible to do this alone. Holding the heavy windows in a height of 7ft and then putting the screws through the hinge in the window is challenging, even with help. But the final result looks really great!

I spend the next month again begging the owner to please send me the remaining line strips. But the same game as before continues. He fobs me on and on. One day I see an interesting post on Facebook from someone who has a similar problem with this guy. We start chatting and he offers, that he can check for my strips, while he is at this company checking for his parts. The whole mission would be really ready for a movie and I could write another page here. But the bottom line is that he was able to take the strips with him (at least partly cut). He packed them and shipped it to me and I only have to do the longitudinal cut that they will fit the depth. This even works with my small Proxxon circular saw bench.

But currently it is still to cold for glueing. Therefore I must wait until end of April to be able to glue the line strips also on the remaining windows. In the meantime I was able to work on the electrical section to avoid getting bored…

With the already trained team from last time, things work way better with the next two windows. Nevertheless, I am really happy when all windows are back in the frame. Just to be sure I remove all screws again one by one from the hinges and put some threadlocker on. It was especially important for the screws in the frame, because these are only tapping screws. All in all some of them have already been overtightened by the manufacturer…

Next I “just” want to install my shutters on the windows. The manufacturer delivered an instruction and all mounting material. First you must glue on an L–shaped angle bracket. The also delivered mounting jig helps in finding the right position. But my first foreboding gets confirmed: If I glue them on this position, the shutters will not fit. Therefore I mount the brackets in the shutters and glue them with the shutter as positioning aid to the window frame. But even doing it this way, the screw hole will not fit to the bracket. Therefore I must file a bit on the shutter mounting holes to correct this.

Additionally you must drill into the window frame to rivet some plastic mounts on. Also you must put double–sided adhesive tape on the frame to glue the shutter to the window frame. After thinking about this for a while I decide to remove the brackets again and glue them on with my Dekasyl glue. Then I will not need an additional tape. While trying to get the adhesive tape off the bracket I realize, that some of them are not in a right angle — and indeed, compared with a right angle they are pretty much off. How can someone build such a flub! Now I know why the mounting holes on the shutter have not fit…

I take a look at the shutter and think, how can I mount them. The best would be, to capture the force going down with an L–shaped bracket on the upper and lower side of the window. Then I have no shearing force on the screws. The screws are only necessary to press the shutter on the window frame.

Instead of the original M4 I use M5 screws, for which the shutters have been originally been designed. However, the shape of the mounting bracket will be way more complicated, because I need to mill two notches in the bracket. The first try doing it manually with just a file worked, but the result was not really convincing. Therefore I ordered a small amateur mill, which is sufficient for such small aluminum parts. Then I start the small series production of 12 brackets, which takes several days. But finally the brackets are finished. The positioning is done again by screwing them on the shutter and putting Dekasyl on the bracket. After pressing them on the window frame, I carefully unscrew the shutter to not move the brackets.

After the glue has hardened out, I put some rubber stripes on the brackets and the window frame. This way I avoid, that aluminum is constantly rubbing on aluminum. I also increase the friction, which reduces the mounting force on the screws.

Now the thrilling moment of the final mounting has come: But everything fits! I carefully tighten the screws and everything looks pretty solid. This setup should also survive real offroad tracks. Unfortunately all this work has set me back now for several weeks…

Next is the work on my entrance stairs. This was built already more than a year ago. But due to all the delays I was not able to test it earlier. There I must learn, that just glueing the mounts together is getting too “soft”. Because I have now riveter nut pliers I am able to place some nuts in my stairs and screw them on. Then I work on the stop bar and finally a locker for my stair runners. Finally I place some mounts for the elctricity and pressure connectors in the storage box. Then I can unmount everything and start my paint job.

Like for the rear storage boxes I use again the Raptor paint for the painting. Again, I must first clean the aluminum, then grind it and clean it again. Then the primer can be put on. The next day I can put on the Raptor paint. Because I must do everything in two runs, the paint job takes two weeks. And because I don’t have enough space, I must split the whole paint job in two. So the painting takes a whole month in total. But I cannot mount the storage boxes before the new pressure tanks are mounted and the gas tanks have been lifted. A friend of mine, who is a professional car mechanic, will help me for this task.

Therefore I can now start with the work inside the shelter! First I start working on the inner separation walls. I build them again in aluminum sandwich, like my entrance stairs back then. They have a XPS core with 20mm and an aluminum U–shape profile running all around, which will be glued on the core. On the outside walls I put 0.5mm aluminum sheets, which will be glued over the whole area to the XPS core. This gives the whole construction a great stability. Then I start to glue the two walls in my shelter. There I must learn, that the shelter walls are not straight and in a right angle! I am barely able to squeeze the two walls in. But the bonding seam is getting very thin at some places. Hopefully this will not be an issue when the material extends! But at least the rear carrier for my bed is now mounted!

Next is the storage area on the passenger side and the inner wall to my bathroom. Additionally I need the support to the rear for the storage compartments there. Slowly things are starting to shape!

The storage area at the drivers side will be build like on the other side. Only the long separation wall is a bit shorter. There will be the door to my restroom, which is a bit behind the door to my bathroom. Finally I double check that my 55 gallon water tank has enough space.

Next are the additional carriers for the bed area. Therefore I glue some aluminum brackets on the wall and use some smaller brackets on the inner walls.

Then I start with building up the small storage area at the top end of the bed. This storage area will have three compartments. Therefore I need three lids. Then I also start building the bottom of this storage box. Finally everything will be glued on the wall and the front cover assembled. For this, I don’t use the big sandwich, because the bare aluminum sheet is sufficient. Then I continue with the lid locking mechanism and the front carrier. Finally I do a test mount of the lids to see, if everything fits. The final assembly will be done once everything is foil–coated.

Now the building of the upper storage can start, which runs all around. First I build the separation walls. The storage area on the foot side will be double as deep as the one at the head end and the side.

Then I continue with the bottom carrier. This one also includes the LED lighting as well as the light switch. There I also install a small tube to run the wires to the rear end of this carrier. Next, I mill a curtain rail out of an aluminum rectangular hollow section and glue them to the carrier. Finally I install 4mm blind rivet nuts for the hinges and the light switch. Now the bottom carrier is ready to be glued on. Because it is a bit heaver, I support it with my construction supports.

Now the work starts on the other side with the deeper storage area at the foot end of my sleeping area. Also there I need the empty tube for the LED stripes power supply. Also I need the blind rivet nuts to mount the hinge. Then I glue the bottom carrier on and support everything with my construction supports. Finally I fill up the remaining gaps to the shelter walls with my special glue to make things absolutely solid. Slowly you can recognize how things will look like with the upper storage.

Now it’s getting thrilling with the middle part. All in all I only have 80mils as bridging gap and the tolerances when building this aluminum sandwich can easily reach this distance. But it fits! Also I need an empty tube for the LED stripes power supply here again. Also another round of blind rivet nuts are necessary to mount the hinges. Then it is time to glue the bottom carrier in. This is again challenging, because it is between the other two carriers and you can easily wipe the glue away from the sides. But slowly I am getting trained to do this and it starts to work out. Finally I fill in the gap with a bit more glue and I support everything with my construction supports.

To complete these upper storage boxes, there are only the upper frames missing. They are build from simple aluminum L–profiles with a height of 20mm. Later, there will also hold the lid locker on. Also here the working tasks before glueing is to clean everything thoroughly, then sand everything and finally clean everything thoroughly again — and as usual to cover everything with tape before to make cleaning after the glueing process easier.

The last step is building the lids. Also these are build as sandwich, but from a thinner material. Otherwise I would run into issues with the lid lockers. First the frame will be glued, then the covering aluminum plates are installed. After the first three are glued, I start with the next three on the rear side and finally the last three on the side. When building the last three I get the idea on how to skip measuring for every cut and I build a “poor man’s” limit stop.

Now I can prepare the lid mounting. First I screw the hinges on the bottom carriers. Then I must drill the holes for mounting the hinges in the lids and install the blind rivet nuts. Now I can mount the lids just for testing. Slowly you get an impression of how things will look like.

The last step is to install the lockers into the lid and the counterpart on the top brackets. Originally, this counterpart will be just screwed into the wood — or into the ceiling like it would be done in my case. But I plan to use the L–profile that is already there, but which is just too thin. To build up material I use aluminum flat steel and I glue thin stainless steel on top. This is to avoid that the locking mechanism will work its way through the soft aluminum. Additionally, I glue small magnets on the lids and top frame to avoid that the lockers will rub due to vibrations and damage itself. Now it is easy to see how things will look alike when it is finished!

Next is the installation of my water tank. I want to avoid to carry that part out of my truck when I must drive to inspection in September, so I continue with the buildup here. As buffer to the surrounding walls I use thin XPS plates. The water tank itself sits on an anti–slip mat. To the front I build a storage box, which will be screwed on the floor and can be removed. It also acts as front limit to the water tank.

While I am waiting for the glue to harden out, I use the time to finally install the cable conduit on the passengers side. Also this one will be glued with two or three spots on the outer walls.

Next day I continue with the water tank mounts. First, I must drill the holes in the floor to install the screwed inserts. Then I screw in the storage for testing — and everything fits perfectly! Then I start working on the upper limit for my water tank. This one will keep the water tank down on any road bumps. On the water tank side I install 0.1” thick L–profiles as limit. On the other side I use square profiles for a better stability. The screw connection should be able to take up all forces. Then I can start to mount everything for the first test. The stainless steel screws receive a special grease on their threads to avoid the infamous cold shut. All screws, also the ones in the floor, will be screwed on with 7ft–lbs. This should be sufficient. Finally I glue some L–profiles on top of the storage box to improve the lid supporting area.

Then I start building the storage box lid. Because this will also be the stair to my bed, the lid will be 20mm thick like the box side walls. As usual I start with the frame around the XPS–carrier. While the glue is hardening out I mount the cable conduits on the other side. Now the back light wiring is finally safe! Then I can glue the cover plates on and finally drill the holes for the blind rivet nuts in the lid for the hinge and the storage box for the locker counterpart. Finally I mount the locker in the lid. Then I am ready to mount the lid.

Next I start building the drawer above the water tank. For this I ordered some heavy duty runners. Unfortunately, you cannot remove the inner runner and there is no chance to screw the drawer in from the side. Therefore I must build some angle brackets that I am able to mount the drawer from below. As usual, the head of my countersunk head screw is too high, so it collides with the runner mechanic. Therefore I must grind down the head of 12 screws. Then I can start building the drawer itself. As usual I start with the frame around the XPS–carrier. Then the aluminum sheets are added. Next are the blind rivet nuts in the bottom carrier and the big hole for the handle. Now I can glue everything together. Next I must drill the mounts for the runners counterpart. Then I can start the final assembly.

…to be continued…
