Arctic/Polar/Cold weather packages.

From the Starcraft brochure:

"Our optional Arctic Package extends your camping season and provides protection against frigid temperatures with its insulated, heated and enclosed underbelly.
For additional protection, the optional full-foil wrap boosts your R-values to R-24 in the floor, R-19 in the walls and R-22 in the roof."

This is close to the Jayco's Polar Package. Also, Arctic Fox and many other TT's have some type of foil-wrap to increase the R-value. Many people use a reflective type of wrap on their TT's windows for better cooling and heating. So the stuff must work.

I would get the Arctic Package for sure.

The Autumn Ridge specifications list the standard insulation as R-7 fiberglass--walls, ceiling, and floor. The bubble wrap will increase that all to R-7.5. There is just little argument about the physics of this. In order for any plastic to attain R-values equal to the airspace, the structural cavity would have to be perfectly sealed. Even in that case, the 2" wall cavity would never be R-19 unless it was filled with Aerogel. That would make the Autumn Ridge a $100K trailer.
