I'll take picture of my setup with the gauge at the end of the hose so you can watch the pressure drop and wait for it to be above what you want in your tire. When it drops to the same point as the pressure in the tire I pull the chuck and vent it until the compressor kicks in.

Although not exactly the same I use one similar to this.
It locks onto the vavle stem so yo don't have to hold it on.

We full time also. It is a compact unit with 50 ft of hose, plenty of cord length to attach to the battery, and a filler with gauge and optional valve stem attachments. You should check it out.

I have one just like that Dan. I have two valves stems that face in and after fighting with it I finally bought the one I wanted to begin with. I always do that.

Deppity, if it's not clear from this thread, Yes, you can do it. The challenge is the compressor doesn't kick on until pressure drops below a threshold and that threshold is typically lower than the tire pressure you're trying to obtain. Not exact numbers but to illustrate, the compressor may stop at 120psi, but not kick back on until pressure drops below 90. If current tank pressure is 100 and you're trying to get your front tires to 110, you will put the chuck on the tire and air will actually leave the tire. So, you have to cycle the air compressor by releasing air until the compressor kicks on and then add air to tire only when pressure is greater in the tank than the tire.

Whew.

I'm going to refer you to another thread on tire pressure. Optimum pressure is based on the tires on your rig and the weight of your rig fully loaded. I usually inflate my rear tires to 102 and fronts to 113. I might go 115 on the fronts, but using the bus compressor that's about as high as I can get. The rears are a lot easier.

TIRE MATH THREAD: Check my tire pressure math??

I'll be glad to help you work through this for your rig if you like.

Here's RV Geek's video showing gauge and valve:

Finally, I'm a big fan of this air hose: 3/8 in. x 50 ft. Hybrid Air Hose-575-50A-HOM - The Home Depot It's lightweight and coils effortlessly.

So Phil...... Do you have a fixed "stash" of items in a storage locker in some part of the country??

Or did you "cut the cord" entirely?

We got rid of everything; no furniture storage; nothing. If we own it, it's in our coach.

Really COMMITTED!

Boowho??

I've mentioned this before but it is (IMHO) worth repeating:

When connecting/disconnecting the hose from that chuck, have a really good grip on the hose. 125 lbs of pressure will blow that hose out of there like a 12G shotgun.

If not gripped tightly, I believe you could easily loose some teeth, major eye damage or something else equally bad.

Just re-iterating the warning. Hang on tight.
