Replacing Roof Top A/C units
We're doing a major renovation of our 10 year old National MH this year, (roof work, slide seals and paint) and I'm thinking about replacing both Duo-Therm A/C units only because they are 10 years old...

If they are working efficiently I would leave them be. When the day comes when one fails the hardest part of the replacement if getting the new on the roof and the old one down. Going with higher BTU units is difficult to judge. If you have too much cooling capacity you will lose the dehumidifying effect and the coach will feel like a cave. Cold and damp. If you do replace them consider going with heat pumps if your camping habits will support the use and additional cost. Spring and fall are my favorite camping times but keeping a supply of propane for heat is something I would like to do without.
The original thermostat should work. More or less it's no more than a dry contact relay that will command the unit to turn on and off. If you do replacement just to be sure contact the manufacture.
As part of the refurb project I would consider looking to see if you can add drain lines somehow rather than the condensate draining on the roof.
