Hello to all super duty members.I have a 2006 F350 diesel super duty. I've been a gm man all my life, but was introduced to the super duty in 2006 and fell in love with it. My friend and I build Factory Five Racing kit cars. So far we have built five, and we trailer them all over the country to car shows. we pull a 28' enclosed trailer, and have done it all in the Ford. The truck has 130,000 miles on it and more than half are towing miles. I can't stress the dependability of this truck enough. It has never broken down or given us a seconds worry. We have gone on trips for as much as 3000 miles in seven days without a single worry. The truck is extremely well maintained, it has a Banks cool air system and an Edge powertrain system. I can't imagine a finer truck for our purposes. Thank you Steve
