Unless you find a fiver with a polar pack most RV walls have just about the same R-Value. One needs to do extraordinary things to the external systems to make sure that water supply and drains do not freeze under continuous sub-freezing temperatures. Folks will also extend their LP capacity by getting larger external stand alone tanks.
Suppliers sell a ceiling vent insulating block that's removable. A lot of heat can escape through the skylight. When you shower, you need to remove the block and run the fan.
As I write this, there is a member out in Yellowstone NP that has just tackled all the challenges that I am speaking about with his RV and winter weather.
