Bottoming out

Unlevel

Level

5.  If it is ever suspected that the air bags have bottomed out, increase the pressure (fig. 19).
6.  Adjust the pressure up and down to find the best ride.
7.  If the vehicle rocks and rolls, adjust the air pressure to reduce movement.

8.  It may be necessary to maintain different pressures on each side of the vehicle. Loads 

such as water, fuel, and appliances will cause the vehicle to be heavier on one side (fig. 

20). As much as a 50 PSI difference is not uncommon.
