Tires off ground when leveled?
Hi, am working on a 2003 Newmar for a friend. When using the automatic hydraulic levelers, is it ok for several of the tires to be off the ground several inches? The levelers are on blocks of wood, ...

If the ground is soft, I would use some sort of safety jacks/bracing to insure the MH does not sink on top of you, if you are working under it. Most hydraulic and electric leveling systems are bolted to the frame/chassis, and are designed to resist movement fore and aft, and sideways. The laws of physics are not changed by lifting a wheel(s) off the ground. Wheels and tires are designed to roll without much resistance. Leveling systems are not. If you lift a wheel off the ground, you are transferring the weight from the tire, to the jack platform, which is usually has a smaller footprint the tire, so you have more pressure on the jack pad per square inch that the tire has. If the MH is leveled, the gravitational force is at right angles. I really doubt there is any danger of a MH moving if you raise the rear end off the ground, if it is on solid ground, and if the ground is that soft, what are you doing on it with a MH?
