That was without the foam top. There was lots of and down (mountain roads), so I could do a lot of engine off coasting and long slow engine braking just controlling speed. That was mostly 15-20mph on the dirt and 40-55mph on paved road. I followed (kept up with) a friend going out to his property last night and only got 22mpg.
What model of Toyota do you have? I don't think that the 22R motors get the same economy as the later 2RZ.
