After much research, I ordered the VIAIR 400P-RV for use on my vehicles and RV and am so glad I did. It works great, is quiet, and came with all the attachments you will need to make the job efficient.

Filled my 285 70R17 tires right quickly. Nice carry case and the hoses more than had enought length to do the whole truck. Very nice product.

For portable compressors this is about as nice as you could ask for. I really like how flexible the hose is. You can tell its quality hose; It doesn't fight you. Everything works great so far.

Excellent build quality and ease of use. First use was to air up two jeeps after a day of trail riding around Florence AZ(one with 32" and one with 33") tires in no time at all!

A great compressor. A lot of power in a little package. Everything you need in one easy to carry bag.

Excellent product. i purchased this to top off my 6 tires on my motor home before I drive (60 pounds each) each day. Works perfect. Also AutoAnything is excellent with customer service I will continue to do business with them.

I had a chance to use the 400P Auto for the first time after airing down my 33" tires. The 400P Auto comes with a pistol grip nozzle. The only thing about the pistol grip is that you have to hold it down to get air. Unlike other nozzles that just lock on to your stem. The air pressure gauge gave me an accurate reading while filling the tires. I aired down to around 20lbs and it took me about 10 minutes to air up all 4 tires to 40lbs. The unit automatically shuts off when not adding air to the tire which helps with not overtaxing the unit when moving between tires, etc. And auto starts up when nozzle lever is pressed. The unit is relatively quiet and was not very hot to the touch after filling up. I struggled with trying to attach the quick connect pieces but maybe that is just an issue for my hands.

This VIAIR has it all. It is reliable, built tough, attractive, and works exceptionally well. It is the only portable compressor I would buy.
