Best Three Season Bottom Floor Insulation
Been trying to wrap my mind about how to go about insulating the bottom of our three season trailer. Our little Sunnybrook Harmony has exposed tanks and I am in the process of installing tank heaters....

Fiberglass insulation "breathes" but it will probably be a real chore getting it installed and to stay in place.
Do you have a coroplast under belly? This material is a vinyl extrusion, usually pleated. If you want to maintain access to the plumbing, wiring, and subfloor, you may be able to replace the original liner with foam insulation board.
The tank area is something I'm working on. I think I've pretty much relegated myself to building a frame around my tanks and drains. Inside the welded steel frame, I'll install 1" (or so) polyisocyanurate foam board and also a skin of light gauge aluminum sheet. I'll have to engineer access to the area to work on drain pipes and valves. I won't worry about making this accessible for tank removal. Tanks last forever.
I figured if I framed in the whole area, I could heat this area as a whole rather than using multiple electrical cable heaters and tank pads. Since this would cover just about the whole under-floor area of the bathroom, it should keep the bathroom nice and toasty. We'll see. Fortunately, work on this won't start until Spring.
