Keep in mind WG's is supercharged...& when he says "spirited" he means TO THE FLOOR!
So yah, 11 sounds about right...that's about what I get kickin' it around town.
On the other hand, I was able to average around 15 on the highway during the Moab voyage...& that's with a supercharger, XL knobby tires, spare on the roof rack, lift, etc...![]()
