I do mean an honest 30mpg on the highway, at highway speeds, hauling bikes. Not 60mph either. That'll get you killed a lot of places. I'm contemplating a vehicle swap, and I'm finding both are requirements, but at odds with each other. Seems about the best you can do for a hauler type vehicle is 20-21mpg. Smaller cars will do the 30mpg easy, but I doubt they get that at speed with a trailer. Am I missing anything? It has to be sold in the US.
