I have a 2025 ram rebel level 2. I noticed on my off-road pages the transfer case says locked no matter. What drive mode. It’s in or even if I have 2wd. Selected. Is this because it’s the shift on demand? Or is there something wrong. Asking because I’m try to figure out why the gas mileage is so poor. Getting 12-13 mpg in at almost 2000 miles now. Running 93 octane. And I’m not hard on the truck
