Losthope in his buld thread here:

On page 1 he has the initial mock up of it, then on page 2 he goes into detail of how he assembled the final set up.
A tad too busy for my tastes, but he pulled it off IMO.
If you go through his entire thread, you will see how he tied it all together trough out his whole truck, to include a matching roll pan in the back of the rig.
I hope this helps, or inspires you.
He is a good guy and I am sure if you PM him he can tell you more !!
Good Luck, and have fun with it
