Hi.. We tow our 5th wheel with a 2004 Dodge diesel which has a 8 foot box.. We just have regular 5th wheel hitch that sits in the center of the bed. With the long box we do not have to worry about the trailer bulk head hitting the cab in a sharp turn. If the truck had a short bed we would have to get a slider hitch (more $) to avoid the bulkhead hitting the cab in a sharp turn. Also I like the extra room the long box has compare to the short box (I do not remove the 5th wheel hitch during our off season). Down side of the long box (when not attached to the truck) is that it is harder to park. When the time comes to trade the truck I will get another long box. Jim2007
