I have a belt driven York on one of my Land Cruisers. 10 years with no problems, great for air tools. At the same time, while I was in Iceland, I got a couple of CO2 tanks. The CO2 is NICE!!!! I can air up a 38x15 from 2 psi to 30 psi in under 5 seconds. With temps in the teens and 20s a 15 lb bottle is good for 12 such air ups. At higher ambient temps it will do even more.
