Yes. 70A Delco 1-wire alt driven at mid pto.Two L&G batteries mounted underneath for the voltage storage. I use it for the heater and two 24V actuators for the v-plow up front.
I have 2 heaters fed off a circulating pump from a Dodge Durango. I also put shut off valves in series so i don't need to drain the cab in the summer. when the wind was blowing in sub zero temps the windows would ice up before I added the second heater and pump.
I have the heater from Curtis that is mounted above my left knee then i added one above my head on the right side. I have them plumbed in series and use the circ pump to feed them. Even with the engine coolant temp that normally runs below 140 I usually end up shutting one heater off because it gets too hot in the cab. They have the pump on ebay for around$37.00
