Air compressor

Does anyone know of a good small air compressor to take with us in our fiver? It needs to put 80 lbs into the trailer tires. Thank you for any imput. I have seen very small compressor that plug into a lighter socket but the ones that I have seen wouldn't do the eighty lbs.

Viair is a 12v compressor that hooks onto the battery. It'll do up to 125psi (which is what my trailer tires take).

They're expensive, but you can't beat the quality.

You can do Viair for far less money and still get the same quality. I've been using the 88p off-roading for years, and now that I own an RV I use it for the TT too. You can't buy the same duty cycle and air volume for triple the price. I highly recommend it without reservation, and at $50 it's a steal.

And don't buy one that uses the lighter socket. That limits the amps going to the compressor, leaving you with a woefully underpowered compressor pump.

I got the Viair 88P, less that $50 on Amazon. Connects to TV battery. 10ft power cord and 16ft air hose.

Hi,

I know it's not as sexy as the Viair, but I have $45 Menards pump/tank combo that stores nicely and does a good job on both tire inflation and blowing out my lines for the winter.

Yes, it requires 120 volts. But ordinarily I can plug it in at home or campground, and it also runs off my inverter if I'm away from those sources.

FWIW.

A little late... but I have a HONDA branded air compressor I carried on the bike. I purchased an adapter to plug into the trucks trailer electrical receptacle. It is used to air up the air bags and emergency tire inflater. I think it would self destruct before it would inflate a large tire to 80 or 100PSI. It is comforting to know it is on board.

Will I have a hard time with the 88P @75psi?

Not at all.

Something to think about... if you add an exhaust brake that utilizes a compressor, you can add a tank and have on board air. I just did it to my truck.

I don't know why it was so cheap but I got a new Viair 450P-RV on Amazon for $139. I'm very happy with it. Among other things, the "RV" version means it includes an extension hose. Other accessory parts may be different, as well, such as the extended reach chuck.

The needle fell off the air gauge after only a couple of uses. I chalk that up to poor gauge manufacturing in China, not Viair's design or manufacturing. It will be replaced for free. In the meantime, I have to detach the screw-on valve connector to check the pressure while inflating. Annoying, but will be short-lived.

They offered an upgrade to a digital gauge for $10 as part of the warranty replacement. I accepted but, upon receipt, had second thoughts because it requires batteries. If it sits unused for a long time, the batteries may be dead at an inopportune time. Better to have a simple analog gauge that doesn't require batteries. That's in the mail.

Also late but for others reading we have a Ryobi 18 volt compressor. Automatic shutoff at setting etc. goes up to 120 lbs max I think. Been working great for us. Was about $40 at Home Depot.

Since we also have 18 volt blower / drill / work light / etc that we keep in the MH it is nice with all the batteries being the same.
