What do you tow? If it isn’t super big/heavy I would get the gas. I just traded a diesel Duramax for a gas 2500 6.6L and put about 5,000 miles towing this summer. A fairly light 26’ bumper pull camper and a bay boat were no problem. I didn’t even miss the diesel at altitude over Cottonwood pass. My diesel was great but the emissions BS was enough for me to be ready to send it down the road. If you are towing heavy and big miles, I would consider a diesel. My mileage was a bit worse than my diesel, but I have never gotten very good mileage with anything I drive (at lease as compared to what everyone else *says* they get).
