Our VIAIR 300P has worked well for our Tacoma tires, easily handles 20-62 psi for rear and 15-45 for front, and doesn't seem to get boiling hot. Plenty warm though. But I let it cool for a few minutes before putting back in the bag cuz I'm paranoid about melting the bag. Sometimes I pour a little water on the fins and let it evaporate. Evaporation: very efficient heat transfer! Hope I don't crack the metal though... hmmm.
I think I picked the 300P because the hoses were a little longer. Reaches fine from the ground in front of the truck back to rear tires.
The one thing I wish I'd done differently is mount the compressor inside the engine compartment. Just one less thing floating around the cab or camper. Wonder if there's a standard mount, or if I bought the wrong unit. The Taco has a nice mounting area, not sure what that's for, but looks handy for this situation.
