The rm100 today was a bust. No 12v
function. We found a rm760 but I can't find anything confirming the 12v
setting other than a schematic but I found the same thing for the 100 and then it didn't have it. Like at all. He's gonna fool with ours more. It's out of the camper in his shop. He's going to try burping it again and doing some hokey pokey then leveling it and trying again. The camper is a 1984. I'm assuming since everything is original except the toilet that the fridge is original too. We have a regular mini fridge we can use in the mean time. Thanks again for all the tips and info.
