Your on board one will be more than sufficient for airing up your tires...save your money for more important things....Dennis

Yep.

The right one will have a tank. Don't even think about a 12v one, and don't get a cheap one.

Buy one that will fit in the basement compartment, runs off of 120 VAC, and has a 50' hose.
The easier it is to get to the more often you will use it.
Your tires will appreciate always being kept at the proper pressure rather waiting until your TPMS says you are under-inflated.
It is not that big of a deal to check your air pressure and it gives you a good chance to do a thorough inspection of your coach before you hit the road.

When I was considering a compressor these were some of the questions I asked myself:

1) How much air do I typically aid?
2) How often do I need to add air?
3) What is wrong with using the on-board air?
4) Do I need to use air tools?

After thinking about it I figured out that I didn't need an air compressor at all as I only add less than 5 psig about twice a year and the on-board compressor is more than adequate for that need.

I do have a Viair portable left over from out TT days that I keep in the Jeep which also works well if needed. However I would not have bought one if I didn't already have it.

Just 50' or air hose and a good infiltrator is all that is necessary.

Yes, 150PSI is strong enough to air up a tire to 110, but if it doesn't have a storage tank, it may take a while. I'd get something with at least a 3 gallon air tank. I've posted this before but it's a really good compressor for the price and it fits in the front bin of my coach perfectly!
