6 VEHICLE STRUCTURE
The body of the vehicle is an integral structure
made of 14, 16 and 18 gauge welded and
braced high tensile steel and stainless steel
members. All stainless exterior panels are glued
to anti-corrosion coated members. The complete
structure is protected against corrosion prior to
assembly. The front and rear caps are made of
molded fiberglass. The main roof is made of high
tensile aluminum panels riveted to the roof
structure. The floor is made of 2 layers of ½" (13
mm) thick plywood separated by a 1/8" (3 mm)
insulation to reduce power train and road noises.
Welding
Since welding is a procedure that may be carried
out either as specific instructions from Prevost or
by an independent decision of the owner, the
following information pertaining to welding
should be read before beginning any welding
procedure. The prohibitions and requirements
outlined below must be followed during welding
procedure:
1. Welding must be done only by a qualified
and experienced person.
2. Adequate ground contacts and shields must
be positioned as required to protect
components from damage due to heat,
contact by weld splatter, arcing, or other
potentially damaging events associated with
welding.
3. The following precautions are to be taken to
protect the electronic control components.
Refer to section 00, paragraph 3:
“PRECAUTIONS TO BE OBSERVED
PRIOR WELDING” in this manual.
4. Always wear the appropriate safety
equipment.
5. Weld in clean and well-ventilated area, and
always have an appropriate fire extinguisher
within your reach.
7 VEHICLE EXTERIOR MAINTENANCE
Regular washing to remove dust and dirt is
recommended. See "Operating Manual" for more
details on washing and cleaning your vehicle.
7.1 CORROSION PREVENTION
Preventive maintenance is a key factor in
avoiding corrosion and must be considered as
part of the regular service intervals. The entire
underside of the vehicle is sprayed with a heavy
application of asphalt base undercoating.
The operating environment the vehicle is
subjected to will largely influence the amount of
dirt and corrosion that will accumulate over a
given period. Corrosion is one of the most costly
factors of part failure and shortened part life. It
is, however, an item that can be controlled when
it is conscientiously looked after and the proper
steps are taken in a timely manner.
Certain areas of the coach are more vulnerable
to corrosion than others, and it is these areas
that should be addressed. For example, the rear
baggage compartment bulkhead in the rear
wheelhousing area contains many key
components and should be examined regularly
for corrosion. Other areas include the front
wheelhousing area and the engine compartment.
Road splash will affect undercarriage, condenser
coil and engine compartment. These areas must
be thoroughly cleaned to remove dirt
accumulations from flanges, channels and
ledges. These places accumulate dirt and salt
