Will my rocker panels be strong enough?

[BK'66Step]

So in the next couple days, I had planned on removing my cab to clean and paint the frame, but now I'm having reservations. My plan was to put the cab on a pair of movers dollys that I got from Harbor Freight, but I'm a little worried about doing that now with the condition of the rockers. I know it's a little hard to tell from the pictures, but do you guys think it would be safe to have the cab sitting on these rusty rocker panels or should I tackle that job first before I remove the cab? Thanks!!
