I am building an airstream-style trailer from the ground up, and I have most of it designed, but I have yet to finalize the frame material/size specifications.
Does anyone have a link to info regarding the type of frame material, the sizing, and any guides on it? I see that C Channel and U Channel are often times used, in varying sizes and thicknesses. What would be a good standard size that is very strong but not excessively heavy? Would like to get a really good starting point for the sides, sub floor and roof as well.
Unfortunately, I am a designer without a lot of experience in trailer frames, I'm really interested to learn as much about this as possible, so even pointing me in the right direction would be much appreciated
