Truck Air bags fill location

I opted for the control valves and illuminated gauge that was an option with my PacBrake air bags and it uses the on-board air system running my exhaust brake.

I mounted the controls below the seat rail, behind the driver door fire extinguisher.



Remove the fire extinguisher and you see the inflate / exhaust switches for each side and a dual needle, two input pressure gauge



Onboard air and the gauges makes it very easy to return the pressure to where it just engages the overload springs by targeting 50 psi every time. I deflate to 5 psi when the camper is off the truck.

We also use the air bags to fine tune the level of the TC after getting part way there with leveling blocks. This usually happens in the dark, in a ski area parking lot, in the snow, so the location makes this quick and relatively dry, with the bubble gauges on the front corner of the TC. The illumination makes it easy to avoid exceeding the airbag 100 psi rating.

Ours are inside the fuel fill compartment. This keeps them out of the elements. The only downside is that the driver front fastgun needs to be moved out of the way to access them.

On my 2008 Chevy there was a convenient hole inside the wheel well on the cab side of the axle, so I mounted the valve there on each side. But I do have an on board compressor so that valve location is just a backup. The down side is, obviously, make sure you keep the cap on the valve.

Both are inside the fuel fill door. Keeps them out of the elements.

Mine were just aft of the mud flaps. I didn't like stooping to fill them. Whether they can go in the gas cap area depends on the amount of room I was told.

Put mine on the back of the truck bed, between the bumper and the tailgate, above the license plate. Done when I had the TT, and still OK to use with TC. I use the handheld air suspension pump that I usually carry on the Harley, very accurate gauge built in, & flex hose to the coupling.

You can purchase with 30, 60 or 100 lb gauge. About $50 at J & P Cycles.

Progressive Suspension 0-30 Lb Gauge-Mounted Air Pump
Simple to operate and extremely accurate
• Produces pressure of up to 200 psi by delivering 7 cubic inches of air per stroke

• Ideal for setting the pressure on air forks, air shocks or anti-dive fork components

• Permits minute adjustments by using a ‘let down valve’

• Features an in-line check valve to ensure a no-leak operation and disconnect

• 0-30 pound gauge

Different truck but it might work for you. I routed mine to inside the cab in the storage area under the back seat. It is out of the weather and not likely to get hit by a trailer hitch or debris in the wheel well.

I put mine inside the wheel well on each side
that way when checking tires I'm right there
to check or fill bags been there for years
no problems Air hose is only about 12" or less :)

I usually have them inside the fuel filler flap. My last ones were installed inside the fenders because inside the fuel filler flap wasn't specific enough for the installer. It's a little strange, but with a bit of black paint on the stem caps, it's ok. They are a bit easier to get to now.

Since I also pull trailers with the camper off I routed each line to the rear and through the holes in the bumper used for the upper license plate mounts. Picked up some extra valve stem nuts for dirt bike tubes to hold the fill valves in place. By having separate fill valves I minimize rolling and I can level side to side. Not too bad to reach with the YC onboard.
