Yeah, I've got an '02 Supercrew with a 5.5 ft bed too. It took me a while to get used to it, but now it looks normal, a standard shortbed (6.5 ft) looks like a long bed, and a long bed (8ft) looks like a school bus!!
Jeff, I'm Gregs brother Alan, If your interested I've got a BRAND NEW Roll-N-Lock bed cover to fit your truck. I can't sell it in my necks of the woods because everyone up here has the longer beds. I'm a dealer for Roll-N-Lock and I'll sell it at cost if your interested. http://www.rollnlock.com/
