Diesel vs. Gasser for towing.

Question for those of you that tow a travel trailer with your 2.8 Diesel:

I Tow a 21' Winnebago Micro Mini (4,500 - 5,000lbs loaded) with my 2016 3.6 CCLB Gasser, and if I keep it on flat ground at 65MPH, I can get about 11-12 MPG pretty consistently. However, the engine is at 4-5K RPM - doesn't seem good for longevity. My worst MPG was less than 10 when I encountered a stiff headwind. Put it in the mountains above 6,000', and it struggles to maintain a 30MPH speed and the transmission quickly gets above 205F.

I am considering a trade-up to a Diesel truck, but debating whether to spend the $$ on a 1500 with a 3.0L I-6 or to stay with the Canyon/Colorado but upgrade to a 2.8L Diesel. I love, love, love the size of the Canyon, and would prefer to stay with this generation truck.

Will anyone share their 2.8L Diesel Travel Trailer Towing experience along with the real world MPG they achieve?

Thanks in advance!
No numbers handy, but I went from a '16 gas to a '19 diesel and it is night and day for towing, both power and mileage.

My 23' is around the same 5,000 lb mark.
