I finally got a 2011 SD on order and ordered the short bed. I am torn between just keeping the truck order as is or changing to the long bed with the factory fifth wheel / gooseneck option. Can't get the factory fiver / gooseneck prep option with the short bed. So if I keep the short bed is it not recommended to install for the fifth wheel stuff on a shortbed? Is the resale value better with a longbed or doesn't really affect it? I understand that towing with the long bed is supposed to be safer and especially if towing a fiver or gooseneck? It is not too late to change the order if I decide to but wanted to get some pointers on this from you guys.
