Man IS THIS a helleva SPIN OFF off a hitch topic !
Okay Doc back to the hitch and with a 6.4 Hemi..........it is available again in 2020 on a Durango SR/T with a 6.4 and a factory option.......as for a cover for your car the one on the back of this SR/T would work and it may be available over the counter in your car's color too?
