yeah when i got my truck the wood was rotted as ive seen with many trucks. I could lift the bed about two inches
And trucks with bags have no wood and somehow manage, on the 62 anyway two of the crossills bolt directly to the frame and one bolt at each corner where we did re-inforce the welds this works for me. Funny you should mention railroad tracks i went for a test ride in another truck over tracks and heard all kinds of noise and his bed was bolted down through the wood
