I was strongly advised not to tie into the coach's air system as it just causes problems. I've heard that several times now.
This is BS as you do not need to "tie into the air system" as you do not open up the system to add a T into a line. I actually use one of my tank drains which are located at the front of the coach. By putting a male quick connect fitting on after the valve I can still open the valve and let any water out although I NEVER get any. Put the female quick connect on your air hose and you have plenty of 120 psi for about $15. You can do the same to the line for airing up the coach if it needs to be towed and it may already have the quick connect so buy the appropriate end to go on your air line..
