When I told my buddies I was doing a 6000 mile road trip in my 4Runner last year, they were surprised and said it would never make it, but when I ask why they couldn't say. I've been doing 12,000 miles each year commuting, so why would some highway driving be any worse? Think of it this way... a 2000 mile trip is basically exactly the same as 6-7 full tanks that you would normally be driving day to day without concern, except on your trip there will be less warm up and cool down cycles. This trip is probably better for you car!
