I recently bought the classic "Pappy" truck. A fifteen year old Chevy half ton, in pristine condition, with low miles. It was owned by a man who simply got too old to use it anymore, and had a set of maintenance records that rival a well maintained corporate jet. It came with an ARE one piece, custom painted, fiberglass bed cover. I had no interest in the cover, and was stunned to find that nobody else in my area did either. I tried Craigslist, and got nothing. I contacted several used cap dealers who refused to take it for free. One even told me that he gets stuck with a handful a year as trade ins, and will pile them up, then crush them up with a backhoe, and load the debris in the dumpster. I eventually found an ARE dealer who took it for free, and commented that he occasionally gets a customer that will pay $1200 for a new one, yet the used ones are hard to give away. I guess the point of all this is that a cover can be pretty handy, but buying a new one piece model may not be the smartest idea. Not to mention that they could be a giant PITA if you plan on removing and reinstalling it regularly.
