I was surprised by my new (new to me) Bravada. I am averaging 15 mpg towing and in the city. I guestimate that I should get close to 20 mpg on the highway. This is a pretty significant increase over my Dakota. I only got 12 in the city with that and 16 on the highway. Plus now, I have a more comfortable ride, and mower POWER, UHHHHH! Very impressed. Mac, the dealership said the Smartrac actually is always in 2 WD and when the front starts to slip, it kicks into 4 WD. I tried it on some sand at the beach the other day. If it kicked in, I can't tell. All I know is that it goes through soft, deep sand real well, so snow should be no problem!
