Even if you "dont" need a drw, you wouldnt believe how the handling is a lot better with any camper.
My father got a lance 850 on a gmc 2500 and when hes going for a trip and i dont need my dually i offer him to take it and he dont even think about it, he likes it so much
Another of my friend got a f350 srw with a lot of mod on suspension :
19.5 tires, stableload, huge sway bar and probly more that i forgot.
He got a ~4500 pounds wet camper and the handling isnt as good as my fully stock drw but timbrens to haul my ~6000 pounds camper.
In a couple of years the kids are gonna leave the house and ill be changing my af1140 for a lighter non slide camper, but even if i can haul it in a 250/2500 ill keep my drw no matter what.
