That is absurd at 3k + GVWR. Go put a 4000+ lb trailer behind a Tacoma and report back on performance, even better if it doesn't have trailer brakes to replicate this. I had a 2019 Ranger with a 20' Airstream WITH trailer brakes, a more powerful engine than a Tacoma and it was workable, barely. Even with trailer brakes coming down a gravel road in Idaho I smoked my brakes on the truck - that was the deciding factor to go 3/4+. On paved / improved flat roads it was manageable....just like those old Toyota Sunrader's were designed for, but going offroad, even on gravel mountain roads you could take a Winnebago on, showed it flaws quickly.A Tacoma is 10" shorter in height than a F350 for starters, and the sleeping berth kinda defines your height over the cab. The rig is just under 10' tall anyway, and it's not pushing as much air out of the way as if it was on a 1 ton. The blower probably doesn't help mpg, but the regear certainly won't hurt.
He mentioned 8500 lbs in that video at 7:57.
I built a camper tall enough to stand in on a '84 1/2 ton Toyota, many years ago. The truck weighed 2500 lbs and had a 1600 lb payload as I recall, and I was well over that (had a roomate and all her stuff). Ya wanna talk about crappy acceleration, hillclimbing, stopping, and handling... but I got 18-20 mpg. If little engines don't get better mpg than big ones, then I bet some engine tuning would fix it.
I doubt your figures are correct, quick search:
What kind of MPG can I expect?
Hi Guys, I just bought a 1986 20.5' Mini-Cruiser with automatic transmission and 4 cylinders. How much mpg should I expect. I've been driving it around town for a few days now. I've gone 46 miles and I've lost a quarter of a tank. I'm getting a little worried. I've read that the needle will go do...

Guys are averaging 9 to 17 most are 11-14 (the better figures are 55 mph or below)....same as my Ranger got towing my Airstream and the same as my Ram 2500 did pulling same trailer, no way this thing gets better than either one of those, particularly out west.
