The link is in the original post at the top. It says that according to the 1970 GM manual of engineering, that a C20 is 8% stiffer frame than a k20. I found that interesting.
Where it applies to me, I always saw large trailers being pulled by k20 trucks. I have never seen on this forum or web, a C20 pulling a 32' gooseneck. I started to wonder if it was because the frame was too weak. But according to the link provided above, my frame is stronger. My question in all of this was, is that statement true? Any reason not to pull. Gooseneck with a C20 coil spring truck? I've seen some c30 trucks , but hey, they are one tons so nobody thinks twice if it will handle it
