Help With Figuring Out Which Trucks Will Work For A Camper

Buying anything less than a 3500 for a TC is poor planning. I started with an 8' pop up on a 1500, it was over GVWR with no people or gear. I moved to an 11' TC on a SRW 3500 this was also over GVWR completely empty but with a full fuel tank. Next was the same camper on a dually but now with a family if five. Still over the GVWR.
Get a 3500 SRW minimum. You'll enjoy the experience more with a dually.
Expense? Bandaids are expensive (upgraded tires, shocks, sway bars, wheels, air bags, etc.)
