Harsh winter prep for full-time RVing?
I'm going to be living in Upstate NY quite a bit, often in the winter, and I'm curious how people in general go about making their skoolie livable in -5 degree weather (yes, negative 5).
We're pretty good at getting through the cold weather with added layered clothing, etc, but the interior needs some isolation still. What would be suitable for cold winters? Rigid foam panels? Rolls of fiberglass or cellulose? How thick would be enough?
And how do people typically heat their motorhome? Propane? Woodstove? I'm looking for the cheapest and most efficient. I think I would mostly find myself off in the woods instead of at an RV park, so wood heat wouldn't be impractical. But I would want to be prepared for heating/cooking when I don't have access to a bunch of wood, too.
I think what I'm ideally planning for is being able to be on-the-road and able to get up and go arbitrarily, so I don't think I can have too much left behind or set up outside (firewood, if any, would need to go onto the roof on a roofrack).
As per keeping the water/waste from freezing, I've seen people use foam panel skirting, but I'm not sure how practical this is, if I'm moving around every few days, in the -5 degree weather. Can the water/waste tanks be covered in fiberglass/etc insulation batts? Can the pipes be covered with insulation as well? Or is heat added underneath, such as via lightbulbs or wires wrapped around the pipes, etc?
