How to level my camper WITHOUT moving it or using blocks?

a good jack is not a one time use item. sooner or later you'll need to change a tire on something (the trailer maybe?) and a jack comes in handy for that.

the oem scissor jack that comes with cars is fine and all, but it's geared to maximize torque so it takes forever to go only a few inches. A cheap 6-8 ton bottle jack will lift 1/4 or more per pump and if the pumping gets too hard, slide a piece of pipe over the handle and boom, longer easier handle.
