It could be the configurable diesel fueled engine coolant preheater upgrade, which also preheats the interior and defrosts/deices the windows. All vans have this device installed in order to help bring the engine up to running temperature in cold weather to reduce emissions, but the standard version comes on automatically when the engine is started at low temperatures, and no driver intervention is possible. This is a different device than the parking air heater, which I also have. This is located on the other side of the van, and is optimized for low battery usage. The coolant heater uses coolant pumps and dash fans, which makes battery usage high and therefor is not appropriate for constant heating when parked.Water Heater with remote sounds a bit interesting. What's that?
