Our first TT was a 1968 Kencraft, it had a propane only fridge in it and when we sold it in 1988 that fridge was still working perfectly. Our next TT was a 1990 Forest River. We ran that fridge on propane only for 15 years and never had a problem. The POs of our current MH changed out the RV fridge for this residential GE thing that has not worked right for us in the 3 years we have had it. Based on past experience I will go with an absorption fridge and run it strictly on propane and should be years before anything needs to be done again.
