How's a dually limit where you can go? It's really not that much wider than the camper itself. I'm not trying to argue or anything, I just don't see that extra couple of inches making that big of a difference. If it's that tight a trail then chances are you're risking damage to the camper itself as well. Am I missing something?
The general consensus is that the dually is less adept at off-roading that the SRW truck. Not only are they wider in the hips, but they also have a wider turning radius. They also don't have the traction capabilities that a SRW truck has (DRW's do float better over certain surfaces like loose sand though). The big negative, however, is that jagged rocks can get stuck in between the tires which can slice through sidewalls. These disadvantages are why nearly all extreme off-road RVs have SRWs.
Dually's do provide superior stability for heavy loads. No comparison. IMHO, where you intend to travel and camp plays a big role in what type of rear to get. If you intend on staying on the asphalt, then the DRW is the way to go. If you intend on going off-road, then I'd go with the SRW.
