Dear Warm Newell Owner, Our 1991 #277 model has three split units, two condensor units under the driver's seat area and the bedroom unit in the cargo compartment. The front two units slide out after you remove the lower pin or bolt. The fill/service ports are easily accessible and any home AC person could service them. Our units use R-22 or you can use R-422B without having to purge the system.
We just repaired all three of our units after the copper tubing rubbed against the steel enclosure or steel wire covers. My local AC fellow did the silver soldering. I ordered the R-422B on Amazon and charged them myself. I do most of my own car AC work, so I have the gauges and vacuum pump already. Email me if you need further assistance. deg
