I can second that. My 4475lb (curb wt) blimpmobile gets 20-22 on the road and 17-18 towing @ 65 mph on 87 PON. The only difference is I drive a bit faster (70 mph speed limit) without.

The really odd part is that all of my cars (see link in .sig) except the Judge get about the same highway MPG (well closer to 24 mpg for the Reatta and Crossie). I periodically drive to South Florida which is 180 miles of flatland turnpike each way so have some pretty good numbers.
