I agree with get the box. That is providing you have a place to store it if your gonna keep it. It will definitely help resale value. A bud bought an old Ford Powerstroke 4X4 to use in his brick laying trade. It was about 10 years old. Had 100,000 or so MIchigan miles on it. The guy he bought it from was a plumber. Had one of those service type box beds on it. When he sold it to my bud, he pulled his service box and put the original bed back on it. What a sight! Here's this ratty, rusty looking cab with a like new bed!!! Being a work truck and him a brick layer, it didn't look new for long!
