Finally decided to mount my heater and arctic cover. Winter is here and I wanted to be warm. Let me know what you think. I am using this heater with a few mods for mounting.
The second link is to the company I got my resistor from. Obviously you can get them wherever you want.
The third and fourth links are the switch with cover I just wanted the cover and the last one is the switch I used.
Even today with temps in the low thirties and 35 mph sustained winds it kept the cab quite warm. I was wearing only a tee shirt and bluejeans and was quite comfortable. I have it hooked to a single pole three position toggle switch. I used a 100 watt 4 ohm resistor mounted on a 1/2x4x4 piece of aluminum as a heat sink for the resistor on one location of the switch for low speed which gives me 14 volts and seems to work well. position two is full voltage and position three is off.
