Every teardrop camper comes standard with a wheeled tongue-mounted trailer jack that levels front-to-back. The jack can also accomplish side-to-side leveling, which only requires moving it by hand to find the flat spot. In extremely slanted spots, rocks or leveling blocks will help to even out the low side. If you are planning on using a roof tent we suggest using rear stabilizer jacks so the people on the roof do not shake the trailer when shifting at night.
