I't getting time to replace the old 2005 cummins dually. I'm thinking about downsizing to a 3/4 ton SRW. The only thing holding me back is that about 6 times a year I'll being pulling a bass boat with a slide in truck camper. With the camper and all I don't know how well a 3/4 ton SRW handle the weight. Only really considering another dodge.

 

A 3/4 ton should do fine with your camper and boat. But if you wanted to help the ride when loaded, you could put air bags on the rear of it.
mine is a 3/4 ton.
