I use 4" aluminum dryer vent. Since it's only a trail truck, sell the NOS fender heater for big bucks and install an M151 heater under the glove box for less than $100. Plus the fender mount heater is vulnerable to damage by trees in the woods. I'd hate to dent an nos heater when someone looking to install one on their show truck.
