My husband says no.... not unless it's been heavily modified. By the time you load it, your camper will be over 2000 lbs
On edit - a NEW ram 1500 has a payload of around 1500#, depending on the model.
I can't help but wonder if the payload stickers are gone because the owner doesn't want you to know? And he may have used the truck to carry the camper - but that doesn't mean it's advised. I also see sad old Class A motorhomes pulling huge enclosed carhauler trailers at our nearby racetrack..... but it's sure something I wouldn't want to do.
Ed, Deb, and 2 dogs
Looking for a small Class C!
