NOTE: Bergstrom does not condone putting batteries under the sleeper bunk. The floor is not
designed to carry that amount of weight and even deep cycle AGM batteries can emit gas under
certain circumstances. Bergstrom can only support batteries being placed in battery boxes or tool
boxes designed to support the weight of the batteries outside the cab of the truck.
Steel Battery Box Installation
Locate the battery box on the frame as close as possible to the sleeper NITE
Phoenix unit. When positioning the box, always keep the top of the box as
close to the top of the frame rail as possible – Some manufacturers recommend
no drilling within 2″ of top or bottom of frame rail. Check truck manufacturer
guidelines prior to drilling.
Using box as template, mark and drill a minimum
of 4 holes. Always use the holes in the rear outer corner area where you have
double walled steel. Of the 3 holes available on each side of the outer most
edge of box, choose the top and center holes on each side (see photo A). Drill
frame rail using ½″ HS bit. Install box with ½″ grade 8 bolts and hardware
provided. Tighten securely.

frame drilling and must be attached to frame rail with bolts (see instructions in the
following steps 2 and 3).
