Billy, I'm not sure I follow, please clarify what you mean by air pressure wide open.
Blowing water out of an RV's plumbing is the same as blowing water out of a lawn irrigation system in that you want high volume and pressure low enough that the system won't be damaged. The more volume (CFM) you can push at a lower PSI the better. 50 PSI or less at 20 CFM or better is about optimal. If you're going to be filling the system with antifreeze it's not necessary to get 100% of the water out of the system.
