I cut them between the two cab supports ... I have full cab supports, but they too now have drain holes in them.

I'm from down South, so I don't worry about salted roads and all that jazz you guys up there in the Land of the Blue Nose have to worry about.
You're saying its WORSE to NOT have backs. I tend to disagree ... no backs = no where for the water to gather = no rust.
And how would "continuous exposure to the elements" be any different on the back side of the rockers than it is the bottom side of the cab ... or the fenders ... or the bed. The reason the rockers rust is because of the poor drainage design GM did on them ... as well as the lower kick panels/cowl drain. I am just eliminating the "trap point." All of my "underside" components have etching primer, sealer and spray-on bedliner on them.
Rust is my last concern under there.
