I've been a Ford owner last 15 years but decided with all the incentives to try a Chevy. Ford quality seems much tougher but with less bells and whistles. Very dissapointed with my find of a 17" spare rather than a matching 18" tire. Ford would never try to sneak something like that by. also drum rear brakes ??? didn't know they even still made them. All the forums I've seen on the 17" spare mention worries about tire rotation. My concern is safety while towing and tearing up 4 wheel drive with different size tires. I got the HD towing package, which by the way does not include towing mirrors as Ford does, how about SAFETY Chevy people?
