the equipment in use. Fuel cells must be empty when
transporting equipment.
2.

the trailer. Typical braking systems are electric, surge,
hydraulic, hydraulic-surge and air.

gvWr — Gross Vehicle Weight Rating (GVWR) is
the maximum number of pounds the trailer can carry,
including the fuel cell (empty).

to the rear bumper (reflector).
5.
Frame Width — Measurement is from fender to
