I'll argue that Arctic Fox is a "gimme" in the quality dept. There are plenty of other 4 Season Travel Trailers that fit this bill, as good as if not better than Arctic Fox. I know, I owned one. I'll take the fit and finish and the overall materials utilized and building/design of Lance any day of the week. I like my Lance trailer far and away from the Arctic Fox. It's cooler in summer and warmer in winter too! Better quality materials used too. Azdel, Lite Ply. Beauflor, Lamilux 4000, Bal Huck Bolted Frames, Pex Plumbing, all nicely put together using precision CNC routers coupled with Solidworks software make for a pricey trailer, but worth every cent!
Heck, Lance even offers a lightweight trailer (2465) with a king sized bed, all in a small package:
