Not recommending this exact model but something like it. Almost all of the manufacturers that sell air bag and or air shock suspensions also sell 12 vdc compressors that are designed to be permanently installed, and are much better than the the little ones you plug into the lighter outlet.

Buy a bottle of nitrogen and a regulator from your local gas supplier and take that with appropriate hoses and fittings. 2000 psi or so to start with.
A 33" off-road tire is about 4.5 cu ft. You want to go from about 1 atmosphere to about 2 atmospheres, which means you need to add about 4.5 cu ft per tire to air back up.
Your smallest tank is 20 cu ft of ambient equivalent gas. This would give you about one all around air-up per tank. The next size up is 40 cu ft and will give you two fill-ups. Both are compact and easy to carry.
Otherwise, use a 12 volt on-board compressor with a tank.

Hmmm, doubtful. The sparkies around here would know better though....
He's better off with a larger portable air tank, 10 or 12 gal, would be enough to get his tires close enough to road worthy, then stop at a gas station on the way home to top them off. I can just fill two tires from about 20 to 32 psi from my 5 gallon one.

To add, I have a dive card, so I'd get a SCUBA tank and an air chuck adapter and be done with it. All off-the shelf hardware and would take me about 5 clicks to buy. If the son SCUBAs, do this.

Why not one of these.
I have installed a couple of them they do an adequate job though still may be a bit on the slow side for tires.....

How about a small generator to power the compressor, or a gas powered compressor? Scuba tanks sounds best

I have a situation similar to your son. The goal is built in onboard air, but until then I am getting by with this:
Viair 400P
Easily transfers from one vehicle to another.
However, be advised, the gauge is a complete POS. Probably reads about 50% of actual. I didn't buy it for the gauge so much as for the portable compressor.
A number of other folks I wheel with operate off of CO2 tanks.
Powertank would be one system to consider.
Alternatively, you can build your own system.
There are plenty of options, but I have yet to see anyone trying to run a 120 VAC air compressor off an inverter. I suspect an inverter capable of supporting that load would cost more than a 12 VDC air compressor of comparable quality to the Viair.

Thanks for all the suggestions. I've passed them on to my son. He's in NE Georgia; i'm in SW Oklahoma, so no hands-on advice or experiments frm me.
