Well, ive owned my truck for about a year now, and finally got the chance to take it on a long trip. I ran out from near Chicago, Illinois to Abbeville, South Carolina over this last weekend. Total miles roundtrip with detours and going through the Smoky Mountains measured 1870 miles. My only upgrades to this truck are a 4 inch exhaust, a superchips programmer and a BHAF. I pulled my 28 foot gooseneck utility trailer (4400 lbs empty) down empty and back with a 65 GTO on it (4200 lbs). Even at 8600 pounds behind me in the Carolinas on some of the 8 and 9 percent grades i had zero problems maintaining speed in 5th gear up 6 miles of grade at a time. All i can say is WOW am i ever impressed with my truck for what it can do. I just figured id rant about it a little bit and post some feedback for anybody considering a similar trip.
