Take a look at ViAir products. I bought a small, tankless unit designed and setup specifically for RV's and is good to 150 PSI. Downside is it cost about $275.00. Small but very professional. Its light weight, comes in a custom canvas bag made specifically for the compressor, 2 - 25 ft hoses, a gauge and two different fittings. Easy to store and handle. Its 12 VDC but connects directly to the battery due to the high amp draw.

Nothing is going to be fast on a 22.5" tire. I have P235 Michelins. I can add 5 psi, say from 95 to 100, in about 1 minute. While its output in cfm is low, it is actually faster than my much larger Bostic compressor that came with a nail gun set.

Good luck. Maybe the Sears option is a good one. Perhaps a taste deal.

I checked out the harbor freight unit today, It is HEAVY ... swung by HD on the way back and the husky isn't too bad for size of weight. I will take a look at the sears as soon as I'm out that way.

Time to inflate is not really important as long as it's not somthing like an hour .. . Somthing that will do in case of emergency if I have to plug a tire and fill it. Assuming I can get at the leak easily of course. If I'm home I have the belt drive compressor that I run the air tools with -- too big to drag along O_O.

I bought the 1.5gal Sears compressor based on testimonials on this forum. It's a bit bigger and heavier than a ViAir 12v unit I was considering, but much lower price. The ViAir is a quality unit, but a single tasker. I can replace my big tank unit at home with the Sears as well as take it along in a coach compartment. My big compressor is 120 psi rated, but won't puff over 93 psi in mile-high Denver.
PS-thanks for the heads-up on break-in procedure, FormerBoater.

Just purchased the Sears unit, works well for inflating the larger tires to 120 lbs pressure.
Look around for sales, got mine at Sears for 84.95 on sale but also check K-Mart as they carry Sears tools

YUP - we have the Sears unit as well, love it!

With it's ACTUAL 150 PSI capability, it works better than my much larger 6 gallon tank type I use in the garage.

Uses? not only the tires, but also the air bags, and occasional need to simply blow stuff out - sure, it's not a "daily user", but then, neither is my spare tire, jacks, or various other tools and stuff we always carry for possible emergency or maintenance use, and I wouldn't be without THOSE, either!

You can buy it online or at your local Sears store. Just get a truck chuck for your rear duals and you will be good to go.

The advantage vs using onboard air is speed. This compressor will top off your tires very quickly.

I'll have to keep my eyes open for a sears sale then. I don't need it right away anyway, still have 10 or more long weeks to wait for the coach

Sears for me. Use onboard air to 110 psi and top off with the Sears unit.

I just bought this Sears unit thanks to all on this and another similar thread. I have read the manual and did not notice anything about a break-in period. Has anyone else ?

I second the Husky unit from Home Depot. I had a smaller Husky unit that only went to 125 psi. Couldn't handle the 110 psi I put into my rear 22.5 tires, so I sold it and bought the larger 150 psi Husky unit from Home Depot while I was in Fairbanks, Alaska.

It also works great to clean our compartments by using an air blow gun especially the battery compartment. Does not take very long to air up any tire.

I have an earlier version of the Sears unit. Mine is rated for 125# and can take the front tires to 120 with no problem. I like the newer model better since it has the screw-on fittings rather than a integrated hose.

You also need to plan on getting a "locking" bi-directional chuck for the unit. I learned the hard way that the supplied fitting is totally useless on the outside dual tire (since the inflation stem points inward and there is no room for the supplied chuck). I have now converted mine to the dual head model. You can identify the "locking" model by looking for what appear to be threads on the inside of the chuck. These threads lock with the threads on your valve stems and you can move back to a safe distance from the tire during inflation (which is what is recommended in your owner's manual.)

I have only used my compressor a couple of times, but the peace of mind it provides is priceless.

My manual is on the MH 100 miles away, but the only way I found out about the break-in procedure was the manual.

It is basically a 15 minute run with no load i.e. you are not building pressure. It is a noisy but one time event.
