Kamper Bob:

Amazingly close to what I had in mind.

Staring at the truck last night I had a minor brain drizzle.

If my top step were located 4 inches down from the top of the cab, it would be completely out of view (a positive).

I was thinking of making the top step about 24 inches long. The second step would then have to split a 18 inch gap and would be 30" long.

A 12 degree Kamm treatment has my last step 8 inches above the back of the bed.

So to get the smooth flow Bondo gets (the wind tunnel says he has set the standard), I'd need three steps added. Front one 18 inches above the ARE tonneau spaced maybe 6 inches back from the cab bulkhead (to allow clearance when the lid is lifted) extending maybe 24 inches. Center plate fourteen inches over the ARE tonneau and 30 inches long. Rear plate 8 inches over the ARE tonneau and extending 6 inches beyond the end of the bed. 80 inch short bed.

A final refinement. I radius over the last 12 inches of each step 0.125 inches. Just a little downward turn for the air flow to help keep it attached. Whaddaya think?
