Extra Storage with tonneau cover

[Forester2]

There was a recent thread on how we cover our truck bed. For me, the Extang Trifold has worked well on last 2 trucks, however the addition of new toys required more storage. I didn't want to spend money on a cap not knowing how long I was going to keep the truck so I came up with this. I saw a couple racks made to go over tonneau covers but the were not cheap. Constructed from aluminum angle and fluted polypropelene this box weighs maybe 30 #s. Not bad for a 70x24x22 case. It extends to bed rail so load seems well distributed. Attached to truck bed rails with 4 Z brackets I made which go under cover. Total weight I intend to carry will be right around 100#s.

Where is the access to the storage box and how does the fold up cover work with it?

I'm just curious but it would not work for me with a fifth wheel.

Cover from same material that goues pver top and is secure with 2 thumb screws and 2 padlocks. First 2 panels fold up to box and are strapped in place.
