I got tired of trying to put 110lb of air into my tires using a 120v compressor and also went for the Viair 450P. I made up a separate pigtail so I can plug it into the 7 pin plug in the back of the truck and now checking tire pressures is a breeze. The Viair units are expensive but incredibly well built and it's comforting knowing I have access to the compressor wherever I am.
