Couple years ago I was going up to the UP with my 95 Dodge Dually and a tandem trailer loaded and went through a sealcoating operation and picked a couple screws in the outside dual. Didn't know anything was wrong until I stopped for fuel and smelled Hot Rubber. Just took the factory jack from under the seat, Jacked it up and changed the tire. Threw the old tire on the trailer and went the rest of the way. Factory jack picked up the truck, Camper and tongue weight just Fine.
