I'd like to hook an air compressor hose with a valve to my air brake tank line, to use while I am sitting still. Would this create a problem with the workings of the compressor, brakes, ect.?
Yeah it wouldn't be a bad idea anyway to put a chock on there. If the motor doesn't run you can hook up a compressor to keep the brakes pressurized when towing. Unfortunately I have a lot of experience being towed.
