Which truck or full-size SUV is the most efficient at towing a 7,000 lbs trailer at 70 MPH on our 100-mile highway efficiency loop? We tested more than a dozen trucks with this identical trailer on the I-76 interstate loop. It’s time to list all of them in one place to figure out how each one stacks up against the other.
As of July 18th, 2016, we changed the rules for our highway towing MPG tests. We got a new 20-foot CM Trailers Cargo Mate and loaded it to a total of 7,000 lbs. This trailer and weight is typical to you want you are towing on your upcoming camping adventure or getting to your next job site.
All of the pickups tested here were crew cab trucks with 4WD. All SUVs were also equipped with 4×4 systems, but we run all trucks in 2WD (rear-wheel-drive mode) and with Tow/Haul driving mode enabled.
