Once upon a time, as in before we lost several quality rvโ manufactures with the market dive in the late 2000โs......there were a few โtrueโ 4 season rvโs. In fact 2 or 3 had a written guarantee down to -20 F.
These were heavy, expensive units. Quality comes with a price, and the majority of the American buying public wanted light and inexpensive. Most manufacturers were happy to oblige!
There are a few pretty good units available today.....but they will be heavier and more expensive.
Thicker sidewalls with higher r value insulation, dual pane windows, higher basement and attic r value insulation, well insulated end caps, vented attic, enclosed, forced air heated underbelly with all tanks, lines, dump valves enclosed within the insulated/heated underbelly, 3/4โ to 1โ thick storage bay doors, tanks and dump valves/lines heat traced, are just some of the things that you should look for!
As many have stated.....most manufacturers use 4-Season as a marketing ploy! They may all be 4-season.....provided you spend the 4 seasons in the Florida Keys! memtb
