I took the ZR2 up 12,000’ Round Top mountain in Lake City. Absolutely love the four low with lockers. Trip average from Oklahoma is over 18 miles to the gallon according to the computer. I love the paddle shift going up and down the highways in the mountains. Not a fan of the “hill descent” setting, it rides the brakes. Also not gonna use the “Terrain” setting, it wants to power brake for you. I love the inclinometer in the HUD.
