For those of us that didn't order the Rapid-Heat supplemental cab heater (2011 F250, 6.7), any suggestion on the best alternative ?
I have the dealer looking into it, but their at a loss and so far I can't get a straight answer into having it install after the fact.
I have a 15 mile drive to work and at anything below -15 below (f) (at least since I put the grill inserts in) I'm wearing my arctic parka, not the best way to get to work.
