Insulation?
Nope, plain old fiberglass insulation is used through out all RVs and RVs have a wall cavity of just 1" so R2 or R3 is best one can hope for.. The exception to this may be some "three season" or "Artic" RVs which may have a bit higher R factor insulation but those come at a higher cost to the end buyer..
There is no fiberglass insulation in the walls of a trailer with laminated walls which all 3 models the OP is considering have, it's white beaded styrofoam. Even if they used extruded polystyrene foam which they don't, thats only an R 3.5 to 5.5 per inch depending on the density.
They claim an R7 but you only get R7 in a brochure out of 1" of beaded styrofoam. As far as 3 season and Artic packages that usually means they add a piece of reflective barrier in the mix, run a half assed piece of duct from the furnace into the underbelly, maybe add some cheap tank heaters, and slap a decal on the side.
