I am not comparing economy to my truck. I never even said that. I said against RATED economy. My truck gets exactly what it's rated at.
You are getting 18 mixed, in a loaded truck? My "gas hog" Tundra was getting mid 16s mixed (4x4 extended cab). Filled with roughly 400lbs cargo/tools + 200ish lb topper. It's not a fuel efficient engine, doesn't even have cylinder shutdown technology. If you load your F150 EB with 600lb payload I imagine you would be getting about the same.
What do you get towing as I am curious? the F150 EB is a great truck if you plan to use it like a car. Once you start using it like a truck and adding weight in the bed/towing, the MPGs drop like a rock. Tell me I am wrong if I am.
