One of these would be pretty slick on a 3rd gen:

 

where ould i get a bed like this?

 

i found this on ebay, but i have no idea where to find one

 

I used to have a link for them but the last time I looked, I couldn't find anything.

I've got to remember to go to this next year. I think I saw your bed somewhere in their vendors list. http://www.ntea.com/index.asp

 

I found a mention at a SEMA link, but I couldn't find the company. In all my looking, it also seemed like they were made only for short beds.

It's a really cool way to add storage. I would get one if the cost were not too high and they made one for a long bed.
