UNSTUCK

The size of your wheel makes little difference when considering gearing. What size tire do you plan on running?

Can you expound a bit on this HUGE mileage increase? How has your driving style changed before and after? What stage tune setting do you get this mileage increase, 1-5? I assume this is highway MPG? What speed do you run? Thanks.

Chuck, I put my 2021 SLT (basically fully loaded, minus sun roof), 6.2 and Max tow on a scale on Saturday. Also, I had about 40 pounds of gear in the bed, and a nearly full tank of gas. Cab was empty while on the scale. Front Axle Weight: 3060 pounds Rear Axle Weight: 2580 pounds My Payload capacity on sticker is 1777 pounds. Curb weight on sticker is 5523 pounds. GAWR front on sticker: 3800 pounds GAWR rear on sticker: 4150 pounds. I then hooked my boat/trailer up. My tongue weight was 780 pounds. This leaves me with 1000 pounds for people and gear to maximize my payload capacity. 390 pounds shifted from front axle to the rear axle. I need to fully load my boat with fuel and gear and then bring my whole family in the truck to the scale to get final numbers. I'll likely max out my payload, but everything else should be okay.
