Crossroads side walls are "hung wall", not vacuum laminated, and is glued in place foam board insulation! In the roof, floors and slides are merely spun pink fiberglass glued in between the walls, with a minimal R-value of R-7..and that spun glass can settle with age leaving "voids" of uninsulated space in the walls. They also ad a thin foil sheet of "astro-foil" which is basically mylar and in order to work needs an air gap above or below it, and in this case does not.
For example the other brands mentioned have as standard 3 times the insulation by as much as R-29 Floors, R-27 Roofs, R-8 walls...all High pressure vacuum laminated vs Crossroads more prone to leaking hung wall R-7.
====================
Just wanted to clear one item up. SooperDaddy is correct, the "astro-foil" that many RV Manufacturers use to "boost" their R Values are only good if the is a MINIMUM of 1 inch air gap between the foil and wall. None of the RV manufacturers provide an "air gap" of 1 inch in their walls. It's a PR promo to convince people of their super high R Values. Standard insulation materials available to the RV Industry will never equal a true R Value 29 or 27.
Remember folks even in the best home insulation it's the "dead air" trapped that prevents the transfer of heat loss. That's why there's such a high thickness of fiberglass insulation in ceilings (roofs). that fiberglass isn't insulating- it's the dead air trapped in the fiberglass.
Happy trails,
