air compressor for inflating tires
VIAIR VIAIR-40046 400P-RV VIAIR Portable I have identified this air compressor as a potential candidate for our integra rv. Have not found specification on its air capacity and pressure ability. ...

Gents,
It's always nice to have "Options" when it comes to having compressed air in our coaches for various reasons. After having (7) different Jeep Wranglers over a 25 year period, and all of them having an engine driven air compressor, it's definitely a force of habit having a good supply of air while out and about.
Yes, those of us who have diesel pusher units have a full supply of air, and the source is of course, an engine driven air compressor. And, many have outputs for use as tire filling stations etc. But, sometimes starting the big beast up, possibly in prepping for an early morning departure, just to utilize the engine driven compressor to top off a tire, might not be looked on too favorable by fellow campers.
So, out comes the "auxiliary compressor". And that can be one of many different models and makes. I'm not a fan of any 12V unit due to the very low CFM output of all of them. Yes, some claim HIGH PSI but, that high psi is momentary at best. High PSI in a volume the size of a basket ball is not overly hard to achieve from one of those. But, trying to achieve high psi on some thing the size of 255 80 22.5 or the 300 80 22.5 is pretty hard to say the least.
Many, including myself use the Sears unit as an auxiliary compressor for such a task. It seems to put out a fair SCFM at a rate that's tolerable for most. As stated, there are multiple makes and models so, just make sure the volume and SCFM is acceptable so you're not there for hours on end, just to top off one tire.
