I'm planning to use threaded rod struts at first for the steps. That way I can experiment looking for the best angle & spacing. The struts should be out of the high-energy air stream, but once I settle down on a design, I'll use something that looks a bit better.

The big question in my mind is how far back should the first step begin. My problem is I cannot just snug it up on the cab bulkhead and expect to be able to open my tonneau lid. I look for the first step to be 6-8" below the cab top and the second one will split the difference.

I'll probably have to breakover and buy a scan gage even if my engine control tuning makes a hash of readings. Maybe the error will be consistent and I can find a "best" configuration and then test it the old-fashioned way for real performance.
