My work truck is a dually. Normally loaded with tools and equipment it weighs about 10,500 pounds. The tool box body on the rear is higher than the cab by about a foot and there's a ladder rack above that. Not exactly like carrying a TC but similar.
I take this truck off road regularly to off grid job sites. I'm often in low range, going thru creeks, over rocks, thru mud, etc. I've been using this truck this way for 16 years. I've gotten a rock stuck between the dual tires exactly once and that was in my driveway at home.
The main draw back for me is the height of the truck. The shorter tires on a dually cause the middle of the long truck frame (crew cab, long bed) to drag on some water breaks.
I used to haul a 4,000 pound 11' TC on a Chevy 3500 SRW; hauled it with that truck for 2 years and then put it on a Chevy 3500 dually. The difference in stability and handling was incredible. I would never want to haul a big heavy TC on a SRW again after having it on the dually.
^ This pretty much has been my experience. Except I've yet to get a rock stuck between the duals and my old Dodge has seen a lot of dirt roads!
