My Neighbor has an extended cab with the 5.5ft bed and loves it, it fits in his garage, tows his camper and has enough room for his home depot and landscaping runs. For people that do construction they do like the 8ft beds, but those are also hard to come by. It seems that dealers don't offer in stock the different bed lengths, I understand small dealers not doing it, but large dealers have 6 1/2ft extended cabs, 5 1/2ft crewcabs and they will have 200 F-150's in stock with those 2 configurations, no Flair sides, no 5 1/2 ft extended cabs, no 6 1/2 ft crew cabs, no 8 ft extended cabs, no 8ft regular. But on the other hand its not like ford advertises it has all these different options for its trucks. I'd bet 70% of the people that buy them for there driveways don't know they can get other lengths.
