Jay2TheRescue: Impressive. I did 40.74 US MPG driving sedately, with only 1 occupant, no A/C. I can't explain how you got 38.6 MPG driving faster with over 600 lbs more weight onboard. My next target is 45 MPG. Call me obsessive :-)
LOL, yeah, it wasn't easy. With 4 large men in the car we were referred to as "1,000 pounds of manmeat". Also consider, we were using the a/c, and we had crossed several mountains... It wasn't easy, but we sure had a lot of fun.
