Resurrecting this post (appreciate the insight Brett & Herman), After many years of not using our coach due to overseas and out of state work, we are newly retired and back on the road. And, we just reinstated our FMCA membership. To start, we have a 2005 40' Monaco Windsor that we bought new from a dealer in California. We just returned from our first real retirement road trip yesterday which entailed Houston to California via Interstate 10 with a return via Intestate 40. Upon leaving Tucumcari on Interstate 40 the coach gave us a Low Pressure warning buzzer at 60 psi. After a couple of minutes of trying to build up pressure on the side of the road (trucks and traffic @ 75 mph)I decided to move slowly along the shoulder to the next off ramp which was several miles away. Fortunately I could run without the brakes locking as I had 30 psi at about 1300 rpm. After pulling off the interstate I was able to build up pressure to normal operating range. Unwilling to carry on with the trip without having a professional look at the air system we found a great repair shop in San Jon NM. (Terry's Service Center). These folks repair over the road trucks. Within just a few minutes of rolling to their yard, the owner had me pull into one of their bays. They put the coach on their lift and started to diagnose the issue. After pulling the air dryer filter they found it to be full of water condensation and oil. They also inspected the dryer body and found it to be clogged with the same gunk. They pulled the drain lines from the receiver tanks and found the tanks to be clear of debris and condensation. So, a new filter and thorough cleaning of the dryer and we are on our way back to Texas. I have an appointment with an RV repair facility this week for several minor issues but a new or "factory" rebuilt dryer and line cleaning is first on the work order. Lessoned learned for me is to have the air dryer filter changed regularly and the dryer body inspected at the same time. Although I'm very keen with respect to maintenance issues I just haven't had the time to run through the systems with a fine tooth comb. I'm hoping retirement will afford me the time now. Safe Travels! Blake

Lundstrom, Hope you have resolved the issue with your front A/C. If not please read on. We had a similar issue with ours last month. Front A/C working fine whilst asleep. Then stopped working once we woke and started our morning routine (coffee & breakfast). Rear A/C no problems. After reading Jim S post above we started a process of elimination and discovered that one of the ballasts of our fluorescent lighting was the culprit. It wasn't one of the 12v lights but rather a 120v house light that is very near the thermostat. Front A/C has worked fine since then. I've already started converting the 12v tubes with LED tubes (easy but expensive) and will convert the 120v fixture as soon as we get back to home base. The conversion simply bypasses the ballast. Result is a brighter light and lower heat and electrical consumption. Jim S......thanks for the tip! We are newly back to FMCA after several years of inactivity (little use) due to out of state and country work. Now that we are "gainfully unemployed" (retired), we plan to spend much more time on the road and be active members of FMCA again. Blake & Deb
