diamond back truck bed covers

[gto109]

has anyone here used one of the diamond back truck covers to haul a 4wheeler with yet?  I really like the idea then when i go shopping for a new camper i don't have to get a toy hauler (cost more for the toy hauler). Hear is a link to what I'm thinking.  http://www.diamondbackcovers.com/truckcover/HD_Cover.asp

I've seen people haul snowmobiles around on those, but not on a 1/2 ton pickup. I wouldn't be very comfortable with that much weight up that high, but that's just me. Otherwise those are a genius concept.
