What kind of mileage can I expect?
I just traded off my 2015 Nissan Titan (which I loved) for a 2002 Chevy 2500HD, 6.6 L. Duramax with low mileage. My Titan got 17 mpg highway or less, and when I hooked up my 18' TT, the mileage dropp...

Here's the issue: when towing, you mileage will be a function of wind resistance more than anything, and that will be almost entirely due to the frontal profile of the trailer. So a "full size" travel trailer, that is, one that presents a roughly 8 foot by 8 foot "wall" to the wind will give you the same mileage pretty much regardless of what you use to tow it. Gas TVs will produce 8-10 mpg, diesel ones will give you 11-14, depending on uphill/downhill, into the wind/with the wind, and pretty much regardless of trailer weight, length, or make/model/type of TV.
Before the nit-pickers jump in, I'm aware there are small effects for other details. My point is that the number one largest and by far most important of the factors in mileage is going to be that 8 foot parachute you are dragging down the road.
I have just such a full-size TT. I used to drag it around with a Jeep diesel, with which I got 25-26 mpg without, and about 14 with the TT. I now use a BMW X5 diesel, with which I get 23-24 mpg without, and (you guessed it) about 14 with the TT. I would bet the OP winds up with the same experience: he'll get 9 mpg with the Chevy, just like he got with the Nissan.
