Air Compressor

I know this subject has been cussed and discussed to the same extent that toilet paper has been addressed but:
Using a lot of the information that I obtained over the years on this forum about air compressors and mine is better than yours I used this info to shop for a small air compressor to carry in my MH.
I purchased a Kobalt 3 gal. model 0200382 110 volt compressor. Its on sale for 129.00 right now. With my military discount of 10% it totaled out to 116.10.
But the good part? It pumps up to 150 lbs and has a cut in pressure of 125 lbs. The SCFM (the important stuff in recovery) is: 4.0 @40 psi and 2.6 @90. I really couldn't notice any slow down as it filled to its 150 lb potential.
I air my tires to 105 lbs and even after letting the air out to 90 lbs for my test, I was able to hold the chuck onto the valve core and the recovery was able to bring my tire up to 105 lbs in about a minute and 3/4...lets say 2 minutes. Needless to say, I'm very pleased with it...its a lot more than I expected.
I'm sure that others have similar experiences with their compressors and I used those experiences to purchase this one. Its not too heavy, perhaps 25 lbs (a guess-ta-mate) and actually very quiet. It has not hose or gadgets with it, just compressor.

    I'm carrying the craftsman 125psi compressor and the truck has a PacBrake 150psi 100% duty cycle. I made a Tee to tie them together for good, fast, air pressure up to a full 125psi.

    hershey, it looks like you have a larger class A, so you have the space for it.
    Wish one of the manufacturers would build a small one gallon compressor with a heavy duty tank that would be rated to 150 psi and mount a 1 to 1 1/2 hp rated motor on it. That would be ideal for us.

    I was concerned with the 1 gallon tank on the unit but it as a unit has outperformed the 5 gallon Craftsman 125 lb unit I borrowed a year ago to top my tires off. I think the 150 lb top pressure is what does the trick. As for space, well it took me 8 years of fulltiming before I gave up the area in a bay needed but the ease of now topping tires off makes it something that I wish I had done years ago. Again, I won't knock any unit that fits the need for the RVer, this one just blew my mind at how really well it handled the topping off routine.

    A 110 3 gallon still takes a lot of RV space. I just make sure I fill up before a trip and check the pressure once in a while during the trip. I carry a 12V direct pump that can provide enough pressure to "limp" to a shop if needed.

    For a full timer it would be different.

    Been using them for years.
    BTW- usually RV trailer tires are pressurized to 65 to 70 PSI MAXIMUM!! Check the sidewall to determine manufacturers specification.
    Here's a couple you can look at:
    Model 97080
    or
    Model 69269
    Happy trails,


    I won't poo poo the Harbor Freight compressors you list but neither would provide the 105 lbs of pressure my MH tires require for the weight they carry. If you can get by with the smaller unit, it makes no sense to buy something much larger.

    Sounds pretty good. I have an older Sears 150# 30 gallon. It is a monster especially when full (amazed what 30 gal of compressed air can weigh). It worked very well for several years but now it can run all day and doesn't get past about 120#. It doesn't shut off unless I turn it off. And it is quite noisy. I will have to check one out. Is it from Lowes? I know they carry Kobalt.

    Just noticed this when investigating:
