Leveling your camper before popping it up is extremely important, not only for the obvious reasons (not rolling out of your bed at night), but because certain equipment like your refrigerator must be level to operate properly. Leveling is required in two places: front to back, and side to side. One is easy, the other can be difficult – but I’ll show you how to make it easy too!
A simple yet invaluable add-on to any popup camper is a bubble level – placed on both the front and side of the camper. This enables you to level your popup before setting up camp. I place both bubbles at the same corner of the camper for easy reference. Leveling the camper from front to back is then easy to do with the tongue jack, and easy to verify with the bubble level.
BAL Tire Leveler
Some people use blocks under one of the tires to level the camper from side to side, but this can be quite a pain. I use and highly recommend the BAL Tire Leveler.
Simply park your camper where you want it, use the tongue jack to level the camper from front to back, and then slide the BAL Tire Leveler under the lowest tire and crank until perfectly level. Here’s a video showing how easy it is to crank:
In addition to it’s leveling function, the BAL device does wonders to keep the camper stable, preventing the wheels from rocking back and forth. I use it 100% of the time, even when on flat ground, for this purpose alone.
