Thanks guys, I'll give em a call about the heat in the rear. Just noticed the curb side rear door has a warning about High Temperatures inside. Right underneath it is the DPF and muffler exhaust tubes. Dang I already had placed my little plastic tool box into it :M Guess that ain't going to work out to well. Good news was I found the service connection for the air tanks (underneath the driver seat compartment). At least I don't need to lug my compressor around any more :B Coming from 5th wheels and OEM ST tires I realize how important tire pressure is.
