Makita
The Makita MAC700 is perfect for running all air tools used in RV construction. (A 240v 2-stage is overkill - squeezers, rivet guns, and drills don't use much air.)
The MAC is very compact, so it doesnt clutter the shop, and it's perfect for taking to the hangar for compression checks at annual.
It's so quiet you'll smile with satisfaction every time it kicks on. My shop is in my basement, and the MAC can run all day without disturbing my wife on the main floor. It's very high quality, so it'll last forever.
The only downside is that it's simply too small for finishing work.

I found a portable unit at home depot today that was a 30 gal, 5.0 CFM unit with a two out regulated supply, but do not know if this will be satisfactory. I'm building a -14, so I'll probably be using a rivet gun often, and some minor spray gun. I'm going to out source the final paint work. I don't want to over buy, but as the compressor is going to be located in my workspace, I don't want it running all the time either.
Can anyone give me some input?
Thanks in advance!

Are you referring to this model?

If so, that's the one I have in my garage. I don't have 240 available and don't own the home, so running new service is pretty much out. I looked at a fairly comparable compressor from Harbor Freight, but the reviews I read indicated that it was quite loud for a oiled compressor. (and while cheap HF tools do have their uses, I'm hesitant for something more complex like a compressor) In the end, I decided it was worth the extra money to get the HD compressor.
The portability is nice; it allowed me some flexibility of positioning. I have it beside a couple kayaks, and if it wasn't portable, it'd be nearly impossible to get the kayaks out, but now I can just roll the compressor out of the way if needed.
It's worked well for me so far, but I'm still on the tail kit, so take that for what it's worth. The only time I get it to cycle regularly while I'm working is if I'm doing a whole bunch of match drilling. It's also pretty quiet, and doesn't bother me if it cycles while I'm working. (except that it does drown out the music, but I can live with that  )

I run this one 97% of the time and it's been just fine. Belt driven, oil fed, cast iron twin cylinder, 5.5cfm @90psi, 115v, 20 gallon. Cheap used on craigslist.
For the other 3% when I'm painting or heavy diegrinding, I run this in the backyard (different circuit plus it's noisy) with an air hose and "T" into my airline. Very cheap used on craigslist. Would love a big 240V but this setup has worked fine even for HVLP painting and everything else I've needed and it was cheap and will be easy to take to the hanger.

Phil,
that is exactly what I am looking at at HD, it's on sale for a little less here in Atlanta right now, so I thought it a good bargain as opposed to the 60 gal at $500 + options.
I do have a 15 Gal roll around now, like the one in Larry's post, that I have used for light work around the shop, so I may keep what I have and see how it works, then if necessary, I'll move up to the 30 gal portable (knowing my luck, the price will go back up just before I decide)....
