It boils down to a choice between performance and fuel burn. For an RV towing something, it's often torque that's more critical.
Back in the 1960's, with 4 children, we bought a Mercury Colony Park Wagon. Seats for 8, 429 V-8 with 4 barrel carb. It got 10 mpg on the highway and about 6 in town. I finally figured out why the in-town gas mileage was so poor.
The carb (a 4-barrel Holley, I think) had a float bowl that held about a pint of gas. If I hadn't take the barge to work, Momma did the rounds of the stores. Five miles here and park for a half hour, then 3 miles someplace else and park for 45 minutes. Without a modern vapor recovery systems, the gas in the float bowl evaporated while she was parked. If you evaporate a pint of gas every 10 or so miles, your gas mileage really suffers.
We finally got rid of that barge after the gas crisis, and got a Chevette for me to drive to work and a Taurus for Momma. Gas bills dropped by about 50%. We now run a 3.5 L Kia Sedona that gets around 20 mpg.
