Hilary made the purchase of my new truck a breeze!
Hilary made the purchase of my new truck a breeze! Quick and efficient and minimal effort on my part. Spent less than an hour at the dealership compared to horror stories of the past with other dealers!
Truck is a Solid vehicle overall.
Has a really Big feel to it. I currently use mine to pull gooseneck trailer. I haven't had a load yet that I couldn't pull. The downsides to this truck is to me I feel it could get better fuel mileage. Also I had trouble with #4 injector...dealership replaced it. Now my AC doesn't work all the time. Although it sounds like it's blowing it isn't.
