Very
I had to pull my 30 year old Dometic because the fan stopped working this past summer. I would like to thank Frank Condelli for the great instructions on his web site. They were very helpful. I used a long stock stick of silver solder and ground a drill point on the end to open up the drain tube which after 30 years it was completely plugged up. I replaced the the fan with a much larger one from Go Westy and cleaned all the fins, tightened the thermistor  on the evap fin which was loose. and installed a small motor inside the box itself. The Dometic is working fine now and I am a Happy Camper.
