Who Daily Drivers their diesel TV?

I'm not sure where you are getting your information regarding the Big 3 and their new gas engines and taking a step backwards. When comparing them with your Tundra ( which admittedly is a fine truck for it's intended purpose ) either of them with gas engine's in 3/4 or better yet 1 ton configuration will out tow the day lights out of your Tundra, and get comparable mpg while doing it. It's far more than just engine HP and torque numbers. It's bigger frame, bigger brakes, different gearing, better transmission, higher payload, better suspension, etc... No stepping backwards at all! And I'd even say that for the weight your towing and being a DD that the gas would be your best bet. Now if your planning to upgrade your RV in the future and don't mind the extra costs associated with the diesel then go for it. And yes, I'm speaking from first hand experience. Had a 2012 F-250 with the 6.2 Gasser and pull a 5th at around 9500# loaded. Truck did fine other than less than stellar gas mileage when towing which is to be expected. I know have the truck in my signature that the 250 was traded in on and it is also my DD. Towing and fuel mileage between the 2 is no comparison and apples to oranges. I had diesels up until the gas 250 since 2003 and just missed being in a diesel trucks and was just not able to adjust to the gas engine towing. So far absolutely no issues and no regrets in 3.5 month's and 3500 miles.
