Just saw this thread, because I rarely get into the v-10 forum, more of the time is in the excursion one.
I guess I have a very rare truck indeed. I lie, I think there are now 3 in Rupert that have the v-10's, but I have the only one in town with the 08 towing mirrors and any upgrades for that matter.
Croozer, where bouts in bc are ya. We also have a bc chapter here:

If ya have any other questions don't hesitate. wallz
I get around 7-8 in town, and that is on short trips as Rupert has nowhere long in town to go.
On the open road I get in the 14-16 depending on how much a press the go pedal. And that is with the 285 mud tires.
