I store my 33 ft camper 4 hours away and same goes for most of my toys, they are in storage in elcheapo places where power is not available. Every winter and spring I am dire straits to air up the darn tires.
So I caved and bought the Viair 450p, this is a 100% duty auto shut off compressor.
Pros: aired up my camper tire from 51 lb to 55 lb in about 50 seconds, I like the auto shut off feature.
Also, it is not that loud, the lines that come with it are pretty nice.
Cons: I have not used it enough to figure it out yet.
I wonder if I can add an inline tank to air it up first while I get ready and use the air off that to air up the tires faster.
I am planning on take the Duramax to sand dunes and using it to air up the tires from 30 lb to 70 lb.
