|Since we weren't
just putting a house on a truck chassis, we could
design a rear suspension that would be well
suited to Motorhome use. In fact, we engineered a
ride system that's nearly as much at home on a
rutted country road as on an Interstate Highway.
You won't find anything like it on any other
There are four rear wheels, in tandem, not dual;
suspended on air, not steel springs. The
combination produces more than just a smooth
ride. It gives the GMC Motorhome a wide stance
for increased stability; as well as keeping the
rear wheels from protruding into the passenger
space. Also, four wheels let us put in four
large, finned drum brakes for added braking
ability. And even the parking brake is applied to
all four rear wheels.
The air springs are located between each pair of
rear wheels so that road shock at one wheel is
passed on to the other wheel. . .not to you.
The front suspension is torsion bar sprung, with
stabilizer bars. And there is an automatic
leveling valve that keeps the rear suspension at
the desired height.
