New technology brings better stuff those days on daily bases.
I am diesel guy but I see that 6.2l is several years older technology, so you can expect more from newer engine.
Beside heavy vehicles, I drive 2 tons sedan who makes 60 mpg on highway and that's 7 yo technology, when newer engine is not only lighter, but more powerful and 15% more efficient.
Since you are buying new, go for the latest.
You would not buy 5 yo cellphone?
For custom build I strongly advise 360 cameras. I also had ultimate tow package, but that was expensive and did not work with camper skirts.

We have one 6.2... a 2017 4x ext cab, and although it doesn't carry a camper.... it tows a trailer, 26' box (read...wind resistance) which is approx 6000lbs. It gets about 8.1 avg in the mountains. Obviously better on the flats.
I have opposite experience. When driving big vehicle in the mountains, driving in 40-50 mph range I am getting very good mpg.
Once I hit flat freeway, the speed goes one way and fuel gauge the opposite.
When I was moving from San Francisco area to Vegas, I made 3 trips with cargo trailer. Going from SF to LV loaded I always had way better mpg, than going back empty, even I always kept my CC at 60 mph. It was all in desert winds.
I think for real life comparison fuelly.com is the best site, even you will find some reports that are way off the line.
But standard procedure for comparing statistics - you ignore the high and low extremes.
The 7.3l owners report between 10.8 and 12.4 mpg
6.2l reports 9.6 to 12.4mpg
7.3 l is newer engine and expected to have better fuel management.
The above numbers are without explanation what load, so most likely empty truck.
Big camper will cut down 30-40%
We can split hair here, but reading the statistics - the higher mpg are reported by owners with just few fill ups, when those with 30-50 fill ups have it going down.
I would interpret that that new owners drive carefully for some time and lower speeds bring higher mpg. Once they start putting miles on it, they start pushing it and mpg drops.
It is also common that new truck is used for grocery getter and showing off, when aged trucks are getting beaten up with hauling and towing.

general comment
You should know that weight differences with different load plays minimal role in highway mpg. They do on city driving.
What matters a lot in highway/freeway driving is frontal area and aerodynamics.
Than last comment about gas engine mpg
"if you have to ask, you can't afford it"
