I'm looking at the Viair 450 100% duty, Thomas 377 40% duty, and I like the Viair 400 33% duty because they say it fills a 5gal tank in 1min 45sec. Whats duty cycle? I'm guessing its the amount of time it can run without overheating, am I right? That would mean you could run a smaller tank with a 100% duty. How many air-ups do you get out of a 5 or 3 gallon tank. I want to mount the tank under that cab on the passenger side, but I don't think a 5-gallon will fit, so I was gonna buy the 3 gallon they sell. Thanks guys for your opinions and comments.
