I just bought a new-to-me 1999 class a winnebago. It has a switch on the drivers dash labeled "Remco". I think it has something to do with flat towing a car behind the motorhome. He was flat towing ...
Someone in the past has used a Remco transmission lube pump ...the Saturn does not require one so it must've been the car before or someone else who had the unit put in there.
