Teardrops n Tiny Travel Trailers

Hi Guys,

Trying to decide what to do in regards skinning the inside and outside of my trailer.

My current plan is to make the walls out of 1 x 1 square tubing, not sure on the thickness probably .065". I will have 1" rigid insulation in between all the "studs".

For the exterior I was planning to either cover it in thin sheet metal or aluminum, I am open to either my question is can anyone recommend a good way to attach the siding directly to the metal? Or will I need to cover the trailer in wood first and then add the aluminum? I would even be open to screwing it on if I could find a screw that was able to survive all the vibrations off off road towing.

For the inside I was thinking of doing the whole thing in 1/4" plywood. Is that too thick for the walls, and to thin for the floor? Would it be better to do 1/2" on the floor, and 1/8" on the walls? Same question as above as well what would be the best way to attach the wood to the metal frame?

Thank you for any help you can provide, while I like the idea of and the strength of the 1" steel tubing walls, it has made finding information for attachment a lot harder for me.

I have attach a image of the farm design showing the insulation, to help with the design. You can also find out more about my design in this thread if it helps. viewtopic.php?f=39&t=61114

My build that I'm in design phase for is very similar construction technique to yours (1" square tubing).

My plan is to use VHB tape and pop rivets. to attach either .04 sheet aluminum or Alumalite.

For the walls, 1/8" is plenty thick and there are lots of choices available in materials & finishing. On the deck, I'm wondering about 1/8" for the floor. It depends on the framing beneath the deck, point loads and other things. "Normal" spacing for 1/2" OSB or plywood on a house build (current code requirements) is for 2' on center spacing, so 1/4" would be 1' on center, etc. Add a layer of foam under that top skin & it changes again. I'm still kicking this one around myself, trying to decide about the 1/8" for a floor.
