Salem 28.5
To my pleasant suprise everything works. Question what is the lifespan of the aircondiner ?

Welcome from Wisconsin and congrats on your '02 Salem.

Depends on make, model, how much time she sat, how much ambient heat during operation, how much operation under low voltage. Use Rv type extension cords but no over 75 total feet if possible. Check for at least 108v at a receptacle during operation. Enjoy your older quality coach.

Depends on a few factors that were previously stated. If it was taken care of and did not see a whole lot of use it will last for a long time (relative to what one considers a long time), I had a 1978 Taurus and the AC worked up to the day I got rid of it and it was the original unit (I got rid of that TT this year) so take it for what it's worth. Each unit is different and it all depends on how good it was taken care of and how much use it has seen.
