And for a decidedly different use for the 'little red box,' I attached air fittings and used it's vacuum ability to drain my water system for winterizing the GMC. Draws all the water out with vacuum, instead of trying to blow it out with high pressure air.
Attach to water heater drain, open all the faucets, turn on air compressor, enjoy watching water leave your coach rapidly. This worked for me for many winters in northern Virginia. Not much need here in Lower Alabama, where the outside temperature is in the upper 60's.
