I rented a nice 1500 Ram to haul a 1300 lb pump to one of my customers I liked everything about the truck but the rear coil suspension. I was on the interstate coming out of Jackson MS heading west and the road is very poorly designed ( not bumpy more like a roller coaster) in that area the handling was squirrely. Just felt real strange.
Limited sample but I prefer leaf springs for carrying weight. Now when the weight was off it road like a nice car so I guess its up to you what you would prefer.
I would never get a 2500 to haul a TC. I drive a 350 dually crew cab a 1997 and I think the ride is very good and love the handling duals provide.
