What buyers say about Viair 400P - 40047 RV Automatic Portable Compressor Kit
It is very handy, and I think the rubber mounts it sits on will last more than a few years, but they are easy to get and replace.
It's perfect to get someone who says their tires are flat or low on pressure off the lot and over to a repair facility in a quick and efficient manner.
The compressor is a great purchase, it comes with a nice bag, long hose, two different attachment heads, and an impressive air gun/gauge setup, all of which I did not have to do.
It was worth it because it is easy to hook up and pack up and run, and because I RV most-time (not full time) and for how often I have to use it.
I used it to keep 6 tires at optimum pressure and blow out the debris from the desert camping after two weeks, but the air did not work.
