Well I just sold my chev dually. It was nice to tow with. Gone to a Dodge 3500 SRW shortbox simply because I live in a complex now that does not allow duallies, plus that one was a chev LB7, and after 4 sets of injectors in 120K, I got sick of it. Loved everything else about the truck. I have wider than stock tires which should help with stability and I am putting Torklift stableloads on it which should also help a lot. Haven't had a chance to test it out as my trailer is in for repairs, but it's only a 25 footer
Oh yeah, most of my RVing is in Mexico, Tolls go by the axles, going SRW just lowered me down a rate class. That was another reason to go dodge, they do not import diesel pickups down there so it tough to get them worked on. Anyone can work on a Cummins. Surw will miss that Allison, though.
