Use leveling blocks or built-in auto-leveling systems to ensure your RV is flat.
The best way to level an RV involves a systematic approach using the right tools and techniques to ensure safety, comfort, and proper appliance function. Begin by parking your RV in the most level spot available at your campsite, aiming to minimize the need for extensive adjustments. Use a bubble level placed on a countertop, floor, or rear bumper to check both front-to-back and side-to-side levels; the bubble should be centered for a level RV.
For side-to-side leveling, first adjust the low side by placing leveling blocks under the wheels on that side, driving the RV onto the blocks until the level shows balance. Use wheel chocks on the opposite side of the lifted wheels to prevent rolling before unhitching. Once side-to-side is balanced, unhitch the RV and use the tongue jack (for trailers) or landing jack (for fifth wheels) to adjust front-to-back level, raising or lowering the jack until the bubble is centered.
For added stability, lower the stabilizing jacks after leveling, but never use them to lift the RV—only to stabilize it once it is already level. If you’re on soft ground, consider digging a shallow trench on the high side instead of relying solely on blocks, which can sink into the ground. For those seeking convenience, automatic leveling systems (like Anderson Levelers or built-in auto-levelers) are highly recommended, especially for full-time RVers, as they simplify the process significantly.
Always avoid common mistakes such as leveling with slides extended, using too many blocks, parking on steep slopes (over 10% grade), or using stabilizer jacks to lift the RV. Communication with a co-pilot using agreed-upon hand signals or walkie-talkies can greatly improve the process, especially when maneuvering into position.
