Ok guys here's my dilema,
I want to put a camper shell on my short bed superduty, and the shell is from a 94 f150. I need to know is this will work... Basically I need the length and width of a later model f150

 

It absolutely will not work. The dimensions for the superduty trucks are longer & wider than the 87-96 body styles. Check with your local campershell dealers & ask them if they have any to fit your truck. Also, ask them to check with their factory to see if they have any to sell at a discounted price. Sometimes they will have some that are returned to them because of color match or other minor issues. You should be able to find a shell for your truck pretty cheap.
