Roof Framing and Skin
The roof frame, like the side framing, is also constructed of bolted aluminum extrusions. The roof rail
is a specially designed curved extrusion which joins the roof and sidewall frames together. The exterior
skin of the roof is a continuous one-piece fiberglass sheet glued to the frame. Refer to the “Body Repair
and Painting” section for repair procedures.
Front Structure
The front structure of the coach is framed with aluminum tubing, curved and bolted together to form a
strong, durable frame to hold the front cap, windshields, and front end accessories. Refer to Frame Re-
pair in the Body Repair and Painting section for repair information.
The front cap which covers the front frame structure is molded fiberglass, manufactured to fit snugly
over the frame structure. Minor repairs to the fiberglass cap can be performed by purchasing a fiberglass
kit as instructed in the Fiberglass Repair section. Major damage to the cap may necessitate the purchase
of a complete front cap from Gillig.
Rear Structure
Two large access doors, enclosing the engine compartment and the air conditioning unit, cover most of
the rear structure. Access doors are discussed later in this chapter.
Rear corner panels, situated on either side of the engine access door, below the end cap, are fabricated of
curved aluminum sheets and are glued to the frame.
The rear cap is fabricated of fiberglass. The cap covers the rear of the vehicle above the engine access
door and the rear corner panels, curves around each side from window height to roof, and curves at the
top to overlap the roof along the rear and on each of the sides. The cap encompasses the rear and side
AC access door and the AC vents on each side. At the left rear corner of the roof, the exhaust pipe ex-
tends through a hole cut in the overlapping rear cap. The cap is joined to the rear panels on either side of
the coach above the tail lights with rivets.
A galvanized steel engine compartment heat shield is bolted to the metal tube frame above the engine
compartment to provide a mounting platform for the air conditioning unit and the inner bulkhead. The
shield forms a protective barrier, shielding the AC system, which is mounted on top, from excess heat
from the engine. Various holes are cut into the heat shield for component placement. UL classified poly -
urethane foam, available from Gillig Parts, is used as a fire sealant on large openings on the heat shield
panel where pipes, cables, and hoses pass through. This shield is not insulated and does not require
maintenance.
The inner bulkhead consists of 3/4” thick plywood with sheets of 18-gauge steel laminated on the engine
side and .05” aluminum laminated on the interior side. Air conditioning system controls are accessible
through the hinged grille in the center of the bulkhead, and vent holes are cut into either side of the con-
trol access. The AC system is attached to the bulkhead with bolts. Silicon fire sealant is used throughout
the AC compartment and the engine compartment in small gaps and corners. One inch thick baryfoil in-
sulation is glued and clamped in place. Special fire-retardant stainless steel transition ducts are mounted
with self tapping screws to the vent holes to provide air flow into the coach.
