12 volt air compressor

Have you looked into the small types that are intended for air suspensions or variable tire pressures on the fly?

I own a Viair 450P portable air compressor that has worked flawlessly for me since 2010. I recommend it highly.

I have a Porter Cable that allows for 125 psi. It is larger than some might like but does not overheat. Works wonderfully. Found it on Amazon and got extra hose and chucks...

450p-RV gets my vote. Also use it to winterize the water lines by blowing them out.

Entirely possible. Sorry if I did, I tried from my memory.

Upon further review, I was wrong. I have the 400P which is faster, but can't be run continuously.

ViAir 400-RV. Heavy duty, it handles everything. The price has come down about 100 bucks since I bought it on Amazon, too.

If you have an inverter use a 115vac compressor. Sure is a lot handier. I converted my refer socket to a duplex so there would be a socket available on both sides of the TT.

One needs to remember there is a 120Vac outlet accessible from outside in the refrigerator compartment, so a short power cord compressor would work on either side of the trailer.

Another vote for the 450P. I had a cheap Black & Decker that did well for a couple years but would not air up my E rated tires to 72 lbs. It finally bit the dust and I went with the 450P. I use it on truck tires, car tires and filling up floats during trips to the lake or river. You can't go wrong.

It all depends upon what you mean by "storable" and "cheap" and "adequate".

The little lunch-box 12V units are hardly capable of filling up a child's beach ball. They certainly are useless at inflating a truly-deflated tire.

I realize that not too many people have the convenience that my Ram truck's "ramboxes" have... but the cheap, $39 Harbor Freight 100 psi "hot dog" 3-gal air compressor fits inside it just fine. The 3 gal tank is capable of inflating a large tire, even from fully flat in a few minutes (as opposed to the 45 minutes from the Sears lunchbox unit that never got the pressure up above 25 psi.) I run my HF hot-dog with a 400 watt inverter. The hot dog also powers my air-powered aftermarket "trainhorns" that warns careless drivers against pulling out in front of a trailer-hauler on the highway. (The trainhorns mfr's compressor costs $400+ but unnecessary with this hot dog plumbed using quick-connectors to the air lines.)

The money saved on that $39 hot dog can be spent on the inverter (less than $25 at Pep Boys....especially with their $20 rebate that brought the cost down to $5.)

The hot dog can be stored in a trunk, or a pickup bed, or a trailer, or .... it's really not that large but it IS a real compressor. (the $39 is the common "sale" price. Ordinary price is $44-$59 but a 20% off coupon is always offered.)

we have a small dual tank campbell hausfeld compressor from lowed. less than $100 to buy. it has a coiled hose that accepts standard air tools. you can buy chucks, with or without gauges, a simple air hose handle to blow your water system empty at the end of the season etc. you can buy the attachments anywhere from harbor freight and walmart to snap on tools. it plugs into the exterior outlet on our AS. I always fill the tanks before we take off. they dont hold enough to fill a tire all the way it you do not have power but it will fill a tire to 40-45 pound which is plenty in an emergency to get to power or a shop.
