Currently in the design stage for my Sprinter and want to include a diesel air heater. I'm wondering if the factory optional auxiliary battery, could be used to operate the fan for the heater. Since this extra battery is in the engine compartment, would it survive the below zero temperatures of Maine and Vermont. I've parked at ski areas where many starter batteries can not get gas vehicles started in the morning. Any insight would be appreciated.
Otherwise, I will put an extra battery or 2 inside the living area under the sofa bed, where the heater is also going to be installed.
I assume I can't use the under the seat location if both seats swivels.
thanks in advance for your time,
Paul
