The interior of the bed was prepped for spray-
in bedliner. Here’s a good DIY tip for this. An
abrasive nylon cup brush on a 4-inch grinder
works great for knocking the shine off paint and
roughing up the surface so the liner grips better
when applied.2
Bedliner Veterans shot the sheetmetal w ith a
black, heavy-textured bedliner material. The
truck came with a plastic drop-in bedliner, but
we’ve found they tend to trap water underneath
and al so warp over time.3
A Smittybilt 2781 5.65-cfm air compressor
was chosen for an onboard air source. The
owner mounted it to a piece of^1 ⁄ 8 -inch-thick alu-
minum plate. A heavy-duty relay controls power
to the compressor, and a 150-psi cutoff switch
was added to kill power once the outlet hose is
fully pressurized.4
The complete compressor assembly on the
aluminum plate bolts onto the side of the
frame using some existing threaded holes. The
compressor assembly is further protected from
theft or damage when the retractable running
boards are in the closed position.5
A solid-state switch panel from Switch-Pros is
used to turn on the main power feed to the air
compressor. The compact panel was mounted to
the dash surface in the cab. The panel also controls
the solenoid signal for the front ARB Air Locker and
will be used for added lighting in the future.2
