I really appreciate all the information Jon. I will have Coachworx evaluate the coach and get the current systems up to speed and add additional cooling systems to the coach if needed to keep it at a habitable temperature in the hot Florida sun. It is strange though that one of the few Prevost specific service centers in North American (the one in South Plainsfield, NJ) serviced this OTR a/c not more than 2 weeks ago with mediocre results...we'll see if Coachworx can do any better.
