Just wondering, I'm going to plug my unit in for the winter and that will keep the motorhome batteries up but the truck battery will be slowly discharged by the computer and from sitting. I will use a pulsing trickle charger, BatteryMINDer Model 1510: 12V-1.5 Amp Maintenance Charger/Desulfator Designed for Cars, Trucks, Motorcycles, ATV, Boat, RV, etc.
