Hi all, I've been lurking on here for a while as I try to plan my build. I'm ready to start the build in the next month or so, probably when I get back from Ireland in April. Ultimately I'm trying to keep the build as affordable as possible. I'd also like it to be reasonably light, but anything around 1000 lbs or less should be fine so I'm not terribly concerned about that part.
So far, my general plan is to build a 5' x 8' on the Harbor Freight 1720 lb load trailer. I'm currently leaning towards sandwich walls 1/8" ply on both sides with 1-by sticks and 3/4" rigid foam insulation inside, using PMF on the exterior. This is where the questions begin. If I go with PMF on the outside, does it matter what kind of plywood I use on the outside? I was planning on using 5x5 baltic birch at least for the roof and hatch since the tear will be 5' wide, but are there any cheaper suitable alternatives? I think I might have started looking at baltic birch when I was thinking about making it a woody.
It looks like I'm going to be building my own doors, the only suppliers I can find of pre-made doors cost about $700 or more for the pair unless someone has other advice or a secret supplier they'd be willing to share.
I plan on getting as many other supplies, outlets, wiring, lights, etc. from a couple of inside sources I have to keep those costs down as much as possible. Are there any other tips you all could suggest? I've seen so many great designs and ideas on here I'm greatly appreciative of having such a wonderful source of information!
Thanks in advance!
