Prolly a dumb question but...do you lift the weight of the camper off the truck before jacking the truck up...never had a flat in all my travels and was just wondering
I carry an 8 ton bottle jack and some wood blocks. I've changed tires a few times on the road. I just leave the camper on the truck, I don't lower the camper jacks, chock the other wheels, put the bottle jack under the axle tube as far outboard as possible, change the tire, lower the truck. Never had an issue with that method, never saw a need to do it any different.
