My Lance 835 slide-in is 12 years old. It was the 2nd to the smallest/lightest camper they made and the sticker says it weighs about 2500 lbs. with water and propane. The total rated weight of my 1 ton SRW is 9900 lbs. That leaves 7400 lbs. for the truck, me, my wife, and all the stuff we load up. I have never weighed it, but I think I'm right at the limit. That's with one of the smallest/lightest campers on a 1 ton!!
There are a LOT of overloaded trucks with campers out there!! Still, 1470 lbs. doesn't sound right. It's a 3/4 ton truck and the HD competition among manufacturers usually meant the carrying capacity was quite a bit higher. But I haven't checked...
