hard side camper like to drive? (cross winds, handling)

Any time you’re buying a one-ton to do nothing but haul a camper, get the dually!!!
Especially if driving in strong crosswinds is your big concern.
I’ve said it before, this is a good time to say it again: I’ve had numerous truck and camper combos for three decades. After the first time I put a camper on a dually, I never have and never will go back to a nervous-driving single rear wheel.

You’re buying new stuff, now is your chance to get it right the first time.
