Mike's Notes
I personally inspected this Ram 1500 Big Horn and I've got to say — someone put real money into building this into a true Colorado adventure truck. The custom steel front bumper with the integrated winch mount, light bar, and recovery hooks is legitimately awesome and would cost you thousands to add aftermarket. On the Carfax you'll see two damage reports: the early 2021 event was light hail damage that was professionally repaired (common for a Nebraska truck), and the 2025 note is minor rear damage — the tailgate has some cosmetic wear but latches, opens, and functions exactly as it should. The prior dealer did a full pre-delivery service including four brand-new tires, fresh oil, wipers, and a fuel system cleaning, so mechanically this truck is ready to go. The 3.6L eTorque V6 with the 8-speed is a fantastic combo for Denver — smooth power, solid fuel economy for a full-size 4X4, and it tows nicely with the 3.55 axle. Come drive it — with the custom build already done for you, this is a lot of truck for the money.
