Towing at 75-80mph is only typical for people who don’t care what the fuel costs or they care but don’t understand the physics of drag. Also, if you think 38s and a lift will yield 12mpg, I’ll be happy to put a clean c-note on that prediction being well below reality.From prior experience, I'm betting that after a lot of these hit Fuelly.com and there's enough data to pull from, the average will settle in somewhere around 24 MPG.
24 MPG isn't bad at all, but since diesel costs more it'll basically break even vs. the Pentastar engine in cost.
Also, the higher the MPG an engine achieves the more sensitive it becomes to change, so the guy who posted his results after towing a trailer above ^^ is going to be pretty typical results with a trailer hooked onto the Jeep OR with 38" tires and a lift on the Jeep. It's going to drive better than the Pentastar due to the large difference in torque output, but it's also going to lose a larger % of it's fuel efficiency than the Pentastar with more load against the engine.
