        Great truck , bad mileage

        by Dream truck owner on 11/8/2026 8:42:28 PM

        This truck has everything you want from a luxury heavy duty truck. The backseat is spacious enough to hold adults on road trips. It's got enough power to tow and haul a trailer fully loaded with wood. Four-wheel drive works spectacularly. All the interior amenities just increase the interior comfort. The seats are fantastic. Two things make it bring it down to a four-star, those are visibility out of the mirrors even with the cameras and fuel mileage which is to be expected with a big V8, just thought maybe even hauling empty, It would be above 16 or 17. All in all fantastic. Comfortable truck, mechanically no issues The infotainment center is a little bit buggy, but that doesn't bother me much. Quick reset and you're good to go…

        Solid and dependable, I still love this truck! Absolutely zero issues. Whether it's load after a home improvement run, pulling the camper into the mountains or across the country, or shifted into 4-wheeldrive...it does its job with excellence.…
