Boxxer 427

HydraMaster Corporation

Vehicle Preparation

hen selecting a truck, remember the preferable vehicle for a Boxxer 427

installation is a cargo van with a heavy-duty suspension package and a half ton

capacity. If a fresh water tank is added, a three quarter ton or larger capacity van,

with a 2,400 pound payload capacity, is required.

TRUCK PREPARATION

The manufacturer recommends the installation of a spray-on bed liner in the vehicle

prior to installation of machine.

Be cautious when drilling any holes through the van floor. Many vans have

critical components mounted directly below the van floor that could be

damaged by a misplaced drill bit. (See Product Support Bulletins 92101, 94062,

and 94063 at the end of this manual.)

This provides ‘metal to cushion’ mounting rather than ‘metal to metal’ and makes for

an atractive van interior. It is highly recommended to install roof vents in vehicles

operated in hot weather locations. Roof vent positions are shown in Figure 1-1.
