I thought some hunters might like to see this rack. I had a lot of people ask about it.
We pieced this truck rack together from some components ordered online. It's from two different manufacturers. The cargo basket is actually a roof rack for something like a Land Rover.
It worked well, hauled a lot of weight. We put the coolers and meat up there and made a lot more room so loading and unloading hunting gear was easy. We had the all the gear for 5 hunters to go from PA to WY and back. (1 traditional gear and 4 with compound gear).
The system allows use of a roll-up cover and access to the bed. Assembly was pretty easy. Cost wasn't too bad. I'm sure there are lot of improvements and modifications that could be made. I couldn't find exactly what I was looking for already manufactured but after using this I'm surprised it's not commercially available as a ready to go bolt on rack.
Note - fastening the runners to the bed rail of a new model F250 is a little tricky. The bed is all aluminum. I used aircraft rivet-nuts.
