Diamond Back Bed Cover?

[goofytim]

I am looking at getting a bed cover for my truck, and have been looking at the diamondback bed cover ( http://www.diamondbackcovers.com/products_tc.asp ). I am not planning on putting a four-wheeler on it, but do like the idea of being able to place heavy items on top. I bought a truck to carry items that would not fit in my wife's minivan. I am also in the Service, and frequent moves are a part of life, so being able to pack items on top of the cover would be a benefit. Does anyone have this cover, and if so do they like it? Does anyone have any other thoughts on the type of cover that would help fit my needs/ wants? I was thinking about getting the Highback cab protector, and placing some additional lighting on it as well. Then I was thinking about getting the whole thing Line-X'd.
Thanks in advance for the input.

I have not run across anyone here or other forums that have these, look nice though.
