Hey Maineah - the second mechanic said they tried to run a code early on and it wouldn't throw one.
Hey - it has 100,000 miles on it. As far as I can tell there is no water damage. We did a thorough search of the walls, nooks, and crannies. The fridge is electrical only. The generator needs to be repaired. I agree with your point about having a price that's low enough since someone will need to put in a bit of elbow work to figure it out.
Hey jjrbus - thanks for the insight. I think this is worth mentioning to a perspective buyer as a potential cause for stalling.
