I don't feel like the V6 offers that much advantage in economy when not towing. It probably doesn't do quite as well with economy towing. There's too little reason to not just go with the larger engine options. Penny wise, pound foolish.
I towed that weight trailer on a cross country trip with the same weight you have. I did it with the Ecoboost 3.5 in an F150. What a pleasure that trip was! I could just about drive as if I didn't have a trailer. A year later, since I knew my truck was capable, we moved up in trailers to twice the weight. I didn't have to buy a new truck again and saved a ton. Don't underestimate how things change.
There's more truth to this the newer the truck is.
With today's high powered ecus, AFM, cyl deactivation, 6-10 speed trans, the gap is even closer.
Although I believed that more heartily until recent. I was used to getting 15-17mpg unloaded in my 2016 5.3 Silvy. Idk if the dealer re flashed it when I had the trans serviced or what, but it's dropped to 13-15mpg immediately. Also everything was reset in the dic which tells me they screwed with something.
on topic, I'd try to drive a couple trucks, v6 v8 same loop same conditions and see what the actual daily driving mpg difference is.
