RVing requires that you be able to inflate your tires, raft, inner-tube, flotation device, air mattress and whatever else out in the middle of nowhere. Master Flow has a neat little air compressor called Q-Max which advertises 120 pounds per square inch of pressure. You connect it directly to your battery and away you go. It has a carrying handle and a built-in gauge.
I don’t care for the cheap plastic coil hose, so I would replace it with a real air pressure hose.
You can pick this up at COSTCO for $50.00. Helping to keep you rolling along - Jim Twamley, Professor of RVing, Dr. of RVology and ROAD Scholar

PSI isn't the important measure. CFM is. That is, how fast does the tire fill up? Look for a rating of 4.0cmf at 90 lbs of pressure. Otherwise, you may spend a LONG time getting that tire filled up.
Mr.Twamley...does the Costco product have a 4.0cmf minimum, and will it inflate the larger RV tire for a Class 1 Motorcoach within a reasnable time???
This product claims to inflate "standard" tires. How does it do with the bigger RV tires? My experience is you must have a bigger air hose line than the yellow one included with this product.
I have had one of these nice compressors for the past 2 years while full timing all over the US. It takes a few minutes to top off the pressure from 105 to 110 psi, typically done about once a month.
Small and compact. I have learned a trick to avoid blowing the 30 amp fuse is to temporarily disconnect the air hose at the compressor when switching to the next tire to reduce the start up load on the compressor. It might not be the right product for inflating a completely flat tire, but you weren't going anywhere fast anyway.
Small compressors like these are not up to the job of filling a 90+ psi RV tire. They can take 10 to 15 minutes just to fill a car tire. I installed a 100% duty cycle (can be run continuously) Viair compressor which can pump up air bags and my large RV tires very quickly. It cost me $200 but now I never have to waste time looking for air.
I just returned this compressor to Costco. The first time in use, it took about 15 minutes to inflate a tire from 100 psi to 105 psi. On the next tire the yellow coiled tubing separated from the black feeder hose which totally disabled the unit. I also realized that all the air fittings are custom meaning you cannot attach a standard air chuck without translator fitting.
This may be a solution for others but it did not work for me.
If you have an AC generator on your RV, get one of the of the small compressors, (possibly a "pancake" style for staple guns) that run on AC, from a home supply store or web company. These typically put out around 4.0 cfm., although they also come in more compact styles. As noted, make sure they will inflate to the pressure of the tires your rig uses, and that your generator can handle the load.
I am trying to fill my RV's tires using a Craftsman 3 gallon,125PSI 1HP compressor. It takes forever to go up a pound. Is there a better device out there for the occasional user? One where the hose screws on and there is a gauge and maybe an auto shutoff? Or at least one of those.
