I am in the planning stages of building my first tear drop. I plan on going with a square drop similar to the hiker trailers but with a 45 degree cut out of the upper front corner. I just bought the steel to weld up the frame and I am planning on welding up a 1" square tube frame for the walls and roof of the trailer. I haven't seen a ton of this but I was thinking of using the composite aluminum sheeting for my walls with no wood. Then putting insulation and some thin plywood or plank on the inside. I wasn't sure if this would be stiff enough though, and that is why I haven't seen much of it. Also, wasn't sure how to attach the aluminum sheeting other than screws similar to a cargo trailer. I figured if this was a good method I would see some people doing it so my main question is why not? Wall strength issues? I am hoping to be one and done on builds.
Thanks in advance, I have enjoyed reading threads so far and have been learning a ton.
