Leveling jacks lift and level the coach. Stabilizers reduce bounce and are not built to carry the RV's weight. Knowing which system is installed, and where each jack sits, shapes the whole assessment.
The jack and control-panel model matters more than the coach brand, because procedures differ between systems and manufacturers publish their own instructions.
Never work under an RV held up only by jacks, and never bypass a leveling interlock to force movement. A coach that sits wrong is a reason to stop, not to push the system.
