We went from a 35' bunkhouse w/ 4 people to a 41' rear LR, front BR with a slide-n-slide for 2 people and love it.. Common folks would say it should have been the other way around, but we bucked that term. In the process we also had to upgrade truck to a DRW diesel. The extra room the new coach provides is awesome. Tho only our 2nd RV, it could be our last as well........at least for a long time. YES it does pose a problem if we want to stay in state and NP's, but don't have a prob if we have to travel a bit more. Many replies all pretty much say, that Botton line it's what ever you feel comfy with and I also like the suggestion about a 38' as a compromise. A heavier coach will ride better and sometimes translates into a better built one. Like what others have said too, advertised pin weight is a misnomer, but on ave, add another several hundred pounds. DO tho go by max GVW for the RV. As an example: our advertised pin was 2800 = actual 3700 (fully loaded). Dry weight is 14,000, max is 16,000, fully loaded, 15,980. Over on all accounts w/ the '15 F350 SRW we had. Yes I MISS the SRW, but the DRW handles the rig w/ ease. Could I have kept the '15? Yes. Legal and safe, NO. I say no cuz if involved in a accident, some sue happy att'y would find out and then it's OS time. Stay within limits of your truck and let the smiles begin.
