Hi Everyone,
I took the long way home by interstate 80% of the way - pretty much following the owners manual guidelines and stayed under 60 mph mostly 55 and less and varying the speed...
Went from Billings, Bozeman to Helena, then home 6 1/2 hours later...
First fillup got around 17.7 mpg. from mostly interstate driving. After filling up went the last 180 miles and still had slightly more than half a tank.
It just fits in the garage in regard to height, plenty of room lengthwise.
H2 Rocks: the lights are a factory option or can be purchased aftermarket also. I ordered mine as an option that was dealer installed.
There are a couple of buttons on the dash, one for the top one like I got, and my understanding is the lower grill ones still haven't come out from GM/Hummer yet.
I think some people use those connections on the dashboard to connect other lights though?
