I tow with a 2014 Grand Cherokee diesel. When not towing, on the highway I get 30 mpg (just did two 1500 mile trips over the last two weekends, Denver to Nevada and back). When I was pulling my 2417 into the mountains and back, I got 21 mpg. Flatland towing was 18 pg. I attribute that to gaining more in fuel economy going downhill than I lose going uphill, so mountain towing is better.

Yes, the diesel engine initially cost more. But, it has paid for itself in increased fuel economy (I figured at about 75,000 miles I was "even").

My 2-cents.
