So my RW has the Flex Air pin box and have questions , what does everyone use to air up ? I have mine in storage and go get every weekend or every other weekend and do mods before we start full timing. And it seems it is low every time I go pick it up , No electricity were my storage is and I wont haul my 120 gallon compressor tank to the storage each time. Has anyone wired a 12 volt compressor in the pin box ? Maybe like one for jeeps or air bags on a truck ? What about airing up tires on the road ? What type of compressor are you using to reach the 123 lbs for the tires ?
I carry around a small pancake compressor, but only use it here and there. I know that Atom Ant ( Brad ) hardwired a pump on the front of his. I am sure he will chime in at some point..
I have a Viair 450P Portable Compressor. I also had to tighten the valve stem on my Flex Air when it was new to stop if from leaking air.

I use a pancake compressor from Home Depot, 150 psi (does my tires too) .
My 1st trip, I stopped at a truck stop to add air and couldn’t get the air chuck on the stem. I did the mod with 1/4 galvanized pipe, painted it black. I didn’t want to drill into the hitch so is used some thin wood held by double face tape. Then I strapped the pipe with a few clamps.
I had added an outlet from my 2000w inverter so I can run the compressor without shore power.

I have a less elegant but light weight solution. I bought the Viar 400P-RV on sale from amazon for $170. It’s continuous duty and will inflate to 150. I added a 7pin plug to the power line so I plug it into the trailer plug harness in my bed. It has a 40amp rating. It’s small enough that I leave it tucked in the back of the bed and it has enough air hose to reach all the trailer tire.
But your right, do make sure it’s aired up before you leave. I forgot once and turned a corner to see the pin box scraping along my bed rail.
I put a dedicated compressor up in the pin box - screwed it right up to the floor.
Vaughan made me some labels for the switches.
I had the parts from messing with other applications, but basically it is an air shock kit from Air-Lift. In retrospect I wish I would have went ahead and installed the WirelessONE controller as well, because I could have controlled it from the cab like my air bags on the truck, and the WirelessONE will continuously maintain whatever pressure you set it at.
Plus, the WirelessONE lets you deflate by momentarily pushing the down button, so you don't have to hold the deflater valve. It's ready when you get out to disconnect. 🙂
