Mike, so far (third season) it couldn't be better, although the DRV isn't a TH. We sold our Raptor because we needed more room. I don't seem to have the same opinion of a dually as do most members as far as stability. (Yes, I certainly do see the NECESSITY of it) It seems to tow about the same as with the F350. We have had good experiences triple towing so that's the way we roll. We are still using our Demco auto-slider with the auto-slide disabled. I'm kind of drawn to the Anderson, but we don't need the bed of the truck so we keep our money in our pocket.
Our RV friends coming in a few weeks run a Tiffin and I've got to ask him about his cargo capacity. I know it's heavy, but I would think the capacity should be up around 3K or so. 350 won't cover the average pop-up camper family...
