Just purchased a 2021 337RLS Reflection last weekend from dealer stock. So far we are loving it. This is the best towing rig we have had, towed it about 60 miles home. We have it sitting our driveway so we can get it setup, just inside stuff, too cold for anything outside. This does do an excellent job of staying warm though! Our other 2 rigs would have been cold in weather like this.
