We tow a 42' 5th with a Ram dually. 27,000 pounds going down the road and 13'5" tall. I usually don't pay attention to the fuel economy as it really doesn't matter (kind of like asking what the fuel economy is of a $300k boat - if you have to ask about fuel economy, you have no business buying the boat). But when I do check MPG towing, it is between 8 and 9 MPG.

If you are truly getting 10 mpg now I'd say you are an exception. I would not expect any more with a 3/4 ton gas. Maybe 2-3 mpg more with a diesel.

The 1 ton/3/4 ton pick ups ride like lumber wagons compared to a 1/2 ton. I think I'd consider sticking to a 1/2 ton for towing a 7500 lb trailer. I agree that the towing fuel economy would be very similar between a 1/2 ton vs a 1 ton. The baby Duramax in a half ton would be best on fuel.

Save your money and buy gas. If vortex generators actually improved fuel economy I think every 18 wheeler in the country would have them.

If I was buying a $300k boat I would definitely be asking what the fuel economy is. Knowing that I can afford something doesn't mean I want to afford it at any cost. I wouldn't order lunch from a McDonalds menu without seeing the prices.

Towing my 12,000 lb 5th wheel with my 2022 Chevy 3500 with the Duramax I get 10 mpg at 65 mph. I could probably get another 0.5 if I slowed down to 60.

Not a $300k boat (well, new they would both be in that range) but we sold our 1.5MPG boat to buy a similar size boat that got 6-10MPG. We gave up top end speed but when you are doing thousands of miles of motoring, it made a lot of sense, especially since marina fuel prices are typically $1/gal higher than on the road.
Also don't run at 75mph with the RV because you can pretty much see the needle on the fuel gauge moving. We aren't in any great rush, so 55-60mph is fine so long as we aren't holding up traffic.

Thanks to all for your replies. The concern with fuel economy is not cost, but range. Trying to gain some confidence that a new gas 3/4 ton (probably Ford or GM) and leaning toward a Silverado w/ 6.6L and 3.73 rear end will go farther on a 34 gallon (or so) tank than the current truck takes me on a 25 gallon tank.

Fuel range is a real issue that is often overlooked and not considered.
