I parked the factory jack 18 years ago and measured and bought a 12 ton hydraulic jack (and jack board) that would fit under the axle on a side that has a flat. Have used it twice for flats. It’s slow and heavy but gets the job done no matter how heavy your camper happens to be. With an axle jack you don’t have to lift that far. The jack board is two, one foot x one foot, 3//4 inch plywood squares glued and screwed together for use on soft ground, sand, or snow. I used to use this board with my rock crawler with the 60 inch high lift jack, but the high lift is now useless with a truck camper.
