Fully liftable hard bed cover?

Working in the oil fields last year, the particular company I was working for then had hard bed covers on the (ford, I believe) trucks. They had a lift system, although I'm not certain if they were spring loaded levers, or a gas shock system of some sort. They attached near all four corners of the bed, and allowed the cover to be raised completely, and level to the truck bed.

I tell ya, it was a sweet set up!! Could work on the tailgate, in shade provided by the raised cover. Raising and lowering was a one man operation.

Has anyone seen anything similar for the Tacoma?

I found a photo (google) of a first gen, I believe, of something that accomplished the same thing, but it looked kind flimsy, and the gas shocks formed an "X" on either side of the bed when raised. NOT what I am really looking for.

Thoughts....
