CLASS C MOTORHOME
13.18 SUSPENSION AIR SYSTEM (OPTIONAL)
Your motorhome is equipped with an air assist
suspension system that can be pressurized to
provide the desired stiffness. Use an air hose
and accurate pressure gauge to pressurize the
system. A valve stem is located on each side of
the motorhome next to the wheel well. Never
operate at less than 20 psi or more than 100 psi.
A good pressure is 50 psi for starters, a higher
pressure gives a stiffer system.
