Not sure on the 18s but you might be able to tie into the 12v charge line on the 7 wire trailer harness. On my 13 once the relay was installed it was live anytime the key was on.

This what was I was thinking, but I think the 2018's have a "smart" connector for the trailer and doesn't activate the wire unless it senses a trailer is connected.

That is also what I had heard, but wasnt sure. Maybe the fuel pump power wire?

I would connect to the battery thru a relay,and the relay switch hooked to a wire that comes on with the ignition on..

Yes, run separate power for the compressor. May not be a lot of amps, but it's never bad to avoid taxing critical circuits.
