The EGTs would start to get up there pulling long grades at freeway speed. My trailer is around 11.5k loaded.
I would use the control circuit for the defrost to trigger a relay for the heaters. No extra buttons and simple..
Except that anytime you run the defrost mode, aka A/C in "mixed" (floor/defrost) mode, you will have the heaters for your mirrors on! Kinda contradictory ain't it? :haha:
