@Kirk W Thanks for all this!
Makes total sense, I didn't think about that. I guess I'll have to go with vinyl.
I found these small dehumidifiers online that I'm hoping will help with this problem but I do cook a lot so we'll see if they're enough.
I've lived in a lot of alternative housing situations over the years and think I can manage with quite minimal electricity. I'm actually at my nonprofit in Ethiopia right now and while heats not an issue, I've gotten pretty used to living with just an outlet or two. I've been looking at the catalytic heaters and am hoping that will get me by without the need for electric heat. I'm okay without a microwave and AC but the lights are a good thing for me to think about. The owners said we might be able to upgrade the garage's electricity in the future but for the start, I'll have to manage on 10amps.
This would be great. The top end of my budget is $6000 (maybe a little more if I find something out of my dreams). On top of that is the composting toilet (1k), the catalytic heater, gravel, skirting, security camera, prepurchase inspection, transport, insurance, greywater system, utility connections, furnishings, etc. I think all the extra things will add up quite fast so I'm trying to keep the trailer itself under $5,000 or $6,000. I wrote one of the inspectors from the website above and he mentioned that prices will drop drastically come September so that was a bit of good news.
*I'll quickly add that I would HAPPILY spend much less than that. I'll be studying for my Master's in Social Work and will be stuck in unpaid internships for two years so I'm more than happy to sacrifice some comforts to save money. Also, for the space I have I need a trailer 18ft or under.
