Use Motorhome to air tires up

FYI I think he addressed or solved that issue in the second video.

I just bleed off the air by partially disconnecting the gauge assy from the air line until the compressor kicks on again. One of these days I'll install the bleed valve!

Just made a quick trip to Harbor Freight and picked up everything I needed to build this for $20, minus the gauge which I already had, and put it together. Works great and will make it a lot easier getting the tires aired up even if I use my compressor at home.

I can't be bothered with using the Cummins engine just to air up my tires.

By the time I drag out the 50 foot hose, hook it up to the air supply fitting in the driver's side fuel/LPG bay compartment, start the engine, rev it up over 1000 rpm and build the pressure up to 120 psi, and then having to keep the engine compressor running so you have enough PSI, THAT is way too much work versus using my portable Husky 155 psi compressor.

Get the compressor out, plug it in and turn it on. Connect up the clamp-on air chuck and let the air begin! A good compressor, various air chucks and a good calibrated air gauge is all I need.

My fronts are at 105 psi and my rears are at 110 psi. The Husky does a fine job plus it get used for many other tasks besides just airing tires.

I still carry that 50 foot hose but it has not seen the light of day since I first tried using the on-board sir system.

Now for those that don't have the room to carry a compressor, then I guess the engine compressor would be the next best idea for airing tires.

I made one up today and it'll also work on the little three gallon pancake compressor I have. That compressor has to often build up air pressure in a similar manner to the onboard compressor.
