This truck (for being just a regular gas consumer vehicle) is nothing short of amazing downhill. I was recently on a trip to NH and driving on 7-12% grade roads. With Cruise control on the truck would just downshift to 3rd or 4th and hold the speed. I have never had a regular vehicle that would just do that on it's own. I was nothing short of stunned to find out it could handle downhill roads this effectively by itself. Every other vehicle was on and off their brakes and this would just hold steady. It was really helpful to me too because I have plantar fasciitis thanks to Uncle Sam so my feet are always in pain so this was just a bonus not having to ride the brakes.
