karl said:'87 chevy 350 powered Grumman 12' step van- loaded to the 10,000# gvw, 130k- (60k on engine and trans) 8.6 mpg avg with a high of 11 hwy in flat FLA.
60-62 mph is the magic number for me as well.
1990 Grumman Olson 16' step van, 7' ceiling, 144K with Cummins 4BT motor. 14 mpg city, 17 mgp Highway at 55 mph. (governor equipped so 55 mph is max)
The negative: I have to wear earplugs on the highway the damn thing is so loud.
