My fifth wheel is listed as 32 foot and change by Heartland, actual outside length right at 38 feet not counting the ladder. I'd say approximately 60 percent of the forest service campgrounds in my area are unavailable to me do to issues getting into the campground itself, or in some cases the access roads themselves. Most state parks and commercial campgrounds in this area are no problem. My wife likes the bigger RV's, I much prefer smaller. Wife likes RV resorts, I prefer small remote camping areas.
As for towing, my 3500 2015 Ram SRW truck handles the 15.5k GVW with no problems. I've pulled over the mountain at Rocky mountain National park, several other passes in Colorado, down to Havasu Az, and all over Utah, Idaho, Wyoming, Nv etc. The gearing on the truck is a little tall so in effect it's only a 5 speed towing. Stability wise, especially with the factory air rear suspension its solid as a rock through the curves, wind, and handles quite well even pulling the mountain passes in the snow and ice.
