Should be pretty comparable to a 3/4 ton big 3 on the MPG and power front. I would guesstimate 11-14 mixed depending on the driver.
15-16 mpg on the highway

That would be my guess too. A 3.5L EcoB HD would do better, plus you would have the boost at high altitudes.
On the other hand, the truck wouldn't have the additional stability of all that weight, nor, I imagine, the engine braking of the Nissan's V8.
I'm not so sure on the 3.5 Ecoboost HD doing better. I had the Max Tow package and because of the terrain I live in (not flat as glass roads) I was constantly in boost. Over the 10,000 miles I owned that truck my average combined fuel mileage was 14.xx. It was pretty comparable to many of the other gas V8's I drove. But I did have the 3.73, 6'5" bed with a CC setup. I'm sure someone will chime in who gets 18mpg, but in my experience when used as a truck they seem to all fall in line within 1-2 MPG of one another, with the exception of the diesel variants.
You're correct. I've had personal and company truck gassers of most every brand and flavor, save for the eco boost over the last 20 years. Prolly 30 different trucks driven in all climates and altitudes and while unloaded highway mpgs have climbed a couple mpg from the 90s til now, fuel maps have been pretty dialed for a long time. No more "dumb" T I systems or spread bore Holleys or quadrajunks pouring gas thru the secondaries.
Once used as a truck, hp per gal of gas is about the same, yet there's always the 55 saves lives group and the perpetual drafters and the embellishers that claim or get exceptional mileage.
No magic bullet for a/f ratios. When your foot is on the skinny pedal the gas guage drops about the same regardless of truck!
