Thanks everyone. Yeah we have had some 80's models campers and class C's and everything worked fine. Of course they could have been replaced. Was just wondering. Hate to be setting in a tin can with no AC for long. LOL Have a great time.
The compressors have been scroll compressors for a number of years now. Fewer moving parts and potential for a longer life.
If you contact the manufacturer they may be willing to give you the MTBF data (Mean Time Between Failure). But with anything mechanical or electrical, it is subject to failure at any given moment.
They are a sealed unit, not like car or home AC, so chances of Freon leak is slim. Big killer is low voltage at RV parks, get a surge protector that will shut them down in a low voltage situation!
