Mille Racer 69

I have a '95 sport sidestep silverado regular 2 door cab with a back seat.
I am having a hard time finding a selection for my sportside, the bed is 6.5' long by 4'1" wide.
I have been looking and the only 1 I can find that may work that will role all the way back giving you full access to the bed is velcrow and I am not so sure about the idea of velcrow being exposed to the elements all the time like that. http://www.autoanything.com/tonneau-covers/truxedo.aspx
Lots of the covers like the snap covers had stretches of supports or something going across the bed and If I need to throw a motorcycle in the back I don't wanna have to take the whole thing off.
I like the idea of the hardtop covers that rool all the way back kinda like a newer garage door but they are too expensive, looking to spend less than $300 but may go over for the right 1.
Does andone have a cover giving them full access to their sportside that they like?
