I have a 2024 Chevy high country 3500 HD and I love it. I've always been a Chevy guy but I chose it over the GMC mainly because I didn't like the GMC grill it looks like a bug catcher. Do your research on an extended warranty but just note, and I learned this a long time ago, that if you were to save $50 a month in a separate account at the end of your 5-year warranty you'd have $3,000 + interest for any issues that pop up or repairs. Just saying!
I agree, no noticeable difference. I've had both. A 2020 HD 2500 high country and I currently have a 2024 HD 3500 high country. Pulling my 5th wheel I actually get 1 mpg better and maybe a little less in town.
I had a 2020 HD 2500 Diesel and also have a 12500lb 5th wheel. Loaded we were right at or a little over on payload. I traded for 2024 3500 HD mainly for the payload increase and Another Jr is correct about the ride both loaded and unloaded. Very happy with the upgrade
