A short update: The CARC paint on my trailer's frame has been removed from the top of the frame rails and the cross members. This will give me a good foundation on which to screw and glue the aluminum frame for the upcoming sleeping quarters. The material that I previously purchased is only 1/8". I now feel that something heavier is needed as a foundation for the body. I'll be going to at least 3/16" or 1/4" aluminum angle for this. The 1/4" would be the wise choice, so the material will probably be 2"x2"x1/4". A new rifle purchase and Christmas has left my cauffers somewhat depleted for now. I do have some things for sale, as I continue to try to downsize my life. Honestly, I really didn't need the extra rifle.
The new aluminum angle should be here soon. I need to get on that. The thought of using plywood in my trailer hurts me to my core but... if done correctly, I see no real downside to it. My planned 1/2" plywood would be a good support inside the walls. It will be waterproofed with quality exterior paint and skinned with fiberglass. Again, like the frame everything will be screwed and glued together and then sealed with Durabak to make it weather tight. The plywood will be skeletonized for rigidity and to lighten it. Foam core insulation will be added to the cutaway sections. The fiberglass will be glued to the aluminum frame to create a waterproof seal at every joint. The plywood just makes sense. Lightening the plywood and reinforcing it with waterproof fiberglass, just makes sense. I've seen many boxes that have been overbuilt with 2"x4" studs, 3/4" plywood and then, skinned with aluminum. They are very heavy. My Jeep cannot handle that kind of weight.
That's it for now. Sorry, it's not much of an update. I do have some great (but expensive) plans for the interior. That has to stay under my hat for awhile longer. My real plan for this trailer is minimalist at every cost. Nothing that isn't a necessity will be added. Both heating and cooling are on the list of things that I want. My heating system is very exciting and an inside shower is also on my list. Not sure if that will happen, as the interior will only be 48" high. We'll see if that can be accomplished and how much space there really is, once the box is formed. I'd like to keep most of the electrical systems 12V. That might not be feasible. I have been doing a lot of research.
Cheers, and thanks for looking!
