Recommendation on sizing external air compressor

[buswarrior]

A busnut needs an oil lubed compressor for aux use.

The duty cycle, as noted by others expensive experience, will wear out an oil less unit.

Remember, for space purposes, you can shed the tank part, you already have lots of tanks under the coach, you just need the compressor bits onboard.

windtrader, curb side, engine door, hopefully, there is a drain valve in there, with a sticker "Drain Daily" that needs draining when you use the coach. Do you have an air drier? If so, get some preventive maintenance done on it, fresh desiccant, purge valve heater check. If not, then you need to have a way to drain the wet tank daily, and WATCH what comes out.

A coach is NOT your father's Oldsmobile, it requires regular worrying over, and all will be blessed.

Ignored, the DEVIL gets to play...

happy coaching!

Once I remove the tank it will fit nicely in the engine side bay once housing the AC. Very easy access to tap the air system from there too
