FYI for those interested.
MPG from the last three fill-ups (250-500mi of driving):
18.5mpg with some towing of a 14' tandem trailer
20.1mpg typical driving, heavier bias toward highway and country roads
19.8mpg typical driving, heavier bias toward highway and country roads
This is about what I was expecting. Not too shabby compared to full-size options from 10 years ago. I'd be interested to see what a 2wd 2.7L EB version could do as a family hauler. Might not be far off many midsize SUV models in terms of economy, but you'd get a lot of room and capability.
