This chapter contains knowledge and information on various components

of your motorhome chassis. Following the guidelines and procedures will
help you to understand and operate your motorhome. Complete instructions
for various components can be located in the operators manual included in
the Owners Information File box.

WARNING: When frame or other welding is involved for

motorhome repair or modification the following precautions are

required to protect electric components in the motorhome chas-

sis.

1. Disconnect the (+) positive and (-) negative battery connection and

any electronic control ground wires connected to the frame or
chassis.

2. Cover electronic control components and wiring to protect from

hot sparks.

3. Disconnect the wiring harness connectors at the transmission elec-

tronic control unit. Open bed storage compartment, open engine
access door. ECU is located above the transmission.

4. Do not connect welding cables to electronic control components.
5. The welding ground cable should be attached no more than 2 feet

from the part to be welded.

The Roadmaster chassis has been designed to provide exceptional bal-

ance, handling and braking characteristics. The Roadmaster rear engine chas-
sis is an engine and frame unit featuring a semi-monocoque tubular all steel
frame design, providing greater structural integrity and more uniform stress
distribution. Incorporated in the Roadmaster chassis is the exclusive air glide
suspension system using eight outboard mounted air
bags and shock absorbers.  The design and set up is
intended to provide the smoothest ride, best handling
and trouble free service, while delivering top notch
drivability. The chassis will also incorporate a three
point hydraulic leveling system or air leveling sys-
tem. The Roadmaster chassis design offers unsur-
passed ease of maintenance and service.

The towing system incorporated in the construc-

tion of the frame is rated at 10,000 lbs towing and
1,000 lbs tongue weight.

The Roadmaster’s exclusive cushion air glide sus-

pension consists of front and rear axles with leading
and trailing arms in a parallel four link arrangement.
A panhard bar is provided for each axle to control
side motion. Each axle is mounted to a wide platform
H-frame which carries the coach body on eight out
board mounted air bags (4 front and 4 rear). Each of the eight air
