All exterior seams in sheet metal below frame, and around the rear wheel well area shall be welded continuous to prevent
moisture from entering compartments. All other interior seams and corners shall be sealed with silicone based caulk prior
to painting.
Only stainless steel bolts, nuts, and sheet metal screws shall be used in mounting exterior trim, hardware and equipment.
Exterior compartments shall have louvers in lower back wall of compartment for ventilation.
ROOF CONSTRUCTION
The roof shall be integral with the body and shall be all welded construction. The roof of the body shall not be less than
3/16" aluminum 3003H-14 alloy tread plate, fully and continuously welded. A 2" rounded radius shall be provided along
the body sides.
BODY SUBFRAME
To assure proper body alignment and clearance, the body subframe shall be constructed directly on the chassis.
The chassis frame rails shall be fitted with 1/4" custom extruded UHMW polyethylene rail cap to isolate the body frame
members from direct contact with chassis frame rails.
The body subframe shall be constructed from 6061T6 aluminum alloy tubing. Subframe shall consist of two (2) 2" x 4" x
1/4" aluminum tubes minimum, the same width as the chassis frame rails. Welded to this tubing shall be crossmembers of
2" x 4" x 1/4" aluminum.
Smaller dimension, lighter gauge tubing or angle material subframe shall not be accepted.
These crossmembers shall extend the full width of the body to support the compartments. Crossmembers shall be located
at front and rear of the body, below compartment divider walls, and in front and rear of wheel well opening. Additional
aluminum crossmembers shall be located as necessary to support walkways or heavy equipment.
To form the frame, the tubing shall be beveled and welded at each joint using 5356 aluminum alloy welding wire.
BODY MOUNTING
The body subframe shall be fastened to the chassis frame with a minimum of four (4) spring loaded body mounts. Each
mount shall be configured using a two-piece encapsulated slide bracket. The two (2) brackets shall be fabricated of heavy
duty 1/4" thick steel and shall have a powder coat finish to prevent any corrosion. Each mounting assembly shall utilizing
two (2) 3/4" diameter x 6" long grade 8 bolts and two (2) heavy duty springs. The assembly design shall allow the body
and subframe to act as one (1) component, separate from the chassis. As the chassis frame twists under driving
conditions, the spring mounting system shall eliminate any stress from being transferred into the body. The spring loaded
body mounts shall also prevent frame side rail or body damage caused by unevenly distributed stress and strains due to
load and chassis movement.
Body mountings that do not allow relief from chassis movement will not be acceptable.
18" REAR STEP BUMPER
The full width rear bumper shall be constructed from 2" x 2" x 1/4" aluminum tubing frame and covered with 3/16" NFPA
compliant aluminum tread plate. The bumper shall extend from the rear vertical body panel 18" and provide a rear step
with a minimum of 1/2" space at body for water drainage.
