      A truck that does what a truck should

      by CJ on Thursday, March 24, 2022

      I want value for my money and a plush ride isn’t on the list of needs. Ford has a great truck but you’re going to pay several thousand more for it. Rams are fine, but not for me. I traded my 1/2 ton Ford for this truck when deciding to get some to get something with more power. I’ve owned Chevy trucks in the past and none of them let me down. Look at the towing numbers on this type of truck and compare it to Ford & Ram. Look at the power plant reliability of Chevy trucks compared to Ford and Ram. When all of that has been researched, check the prices. You’ll find Chevy has an excellent argument to be considered. My buddy who owns a Ford diesel (of the DEF generation) drove mine with a loaded trailer attached and said he was impressed how well it moved. Ironically, it was a car hauler with a Ford on it that was attached. I use it for work, play, daily commute, and long trips. It’ll do all of these things very well. It’s not perfect. This truck has the same rattle by the driver’s left knee that my last truck had. It also has that rear view mirror that auto switches from day to night, and vice versa, that I hate. I hate it during dawn/sunset times when it thinks it needs to be on day and some yahoo is behind me with NASA quality headlights. It also has the same interactive infotainment flaws my Ford had (and I understand all brands have). It’ll shut off on its own and come back a little later. It’s a nuisance that gets frustrating when Google maps is telling me how to get around in city traffix.…

      Great vehicle

      by Isaiah on Monday, December 09, 2024

      I bought this vehicle a few weeks ago and it is a very good truck. It has had no issues and keeps going like a beast. The v8 is powerful and reliable. I have the Work Truck trim and the inside is very easy to clean because of the plastic floor. The android auto works great and I haven't had any issues with it so far.…
