asking my question on here because y'all are the foambuilt experts
I'm hopefully getting ready to head out to Washington for a 3-month travelnursing assignment. While I have 2 acres out there with a small off-grid campsite on it, the assignment is about 150 mi away in Forks and I would be sleeping in my 4x4 Astro van between shifts and going back to my property on my days off.
Do you think PMF would work well and be cost-effective to build a shower / bathroom stall either at the property right outside of my truck camper or maybe even on the cargo rack of my van? The idea would be to have an insulated box that I can set my Mr Buddy in and use a portable hot water heater to take a hot shower before going to work. On the van it would probably be a very small wet bath narrow enough to fit between the taillights of the van but at the property I was thinking about a 4x8 bath house with enough room for a shower and separate toilet / changing area big enough to change clothes.
Whether I go with one idea or both, some of my questions are the same ... How do you get PMF to dry in a cold and humid marine environment like the Pacific Northwest in the wintertime? Is there a problem with frequent exposure to moisture like inside a shower? For the stationary shed, is it necessary to frame it or will it be strong enough by itself since it won't be mobile, at most portable if I move it from one part of the property to the other? Do I need to PMF the inside or maybe just a couple of heavy cuts of waterproof paint?
Any help for information would be appreciated
