Summary towing a measly 6,000 lb camper:

Hummer: ~128 mile towing range (Epic Fail), Price $114k

Ram/Cummins: 9.7 mpg (Fail), Price $68k

Summary: No earth shattering news on the EV, but what was surprising was the underperforming cummins with a disappointing 9.7mpg towing this small camper that has a aero front end.

Traveling on frontage roads and towns at first then towing at 70mph not a big surprise on the mileage. The click method is just stupid. I fill my RAM to the top all the time so I know exactly what MPG I am getting. Tow behind trailers eat more fuel than 5er's.

Wonder what tires they have on the TT, are they 65 mph rated?

That's almost not believable from the Cummins. I had an '04 towing a 5k trailer and never got less that 18mpg. Something wrong with that engine.

I think you're figuring Canadian gallons or something. I get about 14 mpg towing, whether its a 3K enclosed trailer or a 10K dump trailer with my 7.3 diesel F250. I expect your truck would do about the same. I'd also expect that a pre-emissions motor should do better mileage wise than a new one, although our older trucks don't have nearly the power.

I think it's all anecdotal, but there have been quite a few posts over the years that indicate just that. Speculation has been that the fiver is very close to the truck, reducing drag, despite being taller.
