i have an 06 1 ton dodge with almost 69,000 miles on it. i got it in feb. 06 from then till july 06 i pulled campers and trailers that was how i paid the bills. it is an auto didnt think i would like that but i like it pretty well. i havent had any problems at all out of the truck. i ran up and down the road with chevys and fords pully exact trailers. it still has the stock pipe but i did put a cold air kit on it trust me when i say it will out pull the other 2 any day of the week.
