What makes a 4 seasons trailer
We currently have a Rockwood 8313SS and for what we do now it suits us. We have been looking at dealerships and camping shows for 4 seasons trailers. Of course we find each brand has their definition ...

The "4-season" naming came into existence to allow for a saleable upgrade in place of traditionally insulated and configured trailers. In today's TT's it usually means foam filled walls, some extra insulation in floors and ceiling, and may include multi-pane windows (not always).
Insulation values are calculated as to the dimension of the structure and the materials used to fill it. Most RV's have an expended foam material for insulation. Some aluminum sided trailers use spun fiberglass batts. Some use a combination of both.
A newer material used is an air-filled plastic film with a radiant reflective barrier on one side. Generically, it could be named Reflectix. The makers of Reflectix claim that the 1/4" plastic film can have an R-value of R-38. This would be true if the space insulated was more than 6" and the space behind the barrier was a vacuum-sealed chamber. To date, there is not such a space so their claims are not correct. Some RV mfg's push those claims into their build sheets and the buyers believe it. A few nights in cold weather will displace the claims quickly.
