Perhaps my use of the word porpoising was just the wrong terminology and that set you off. What you are describing is what I am observing.

Now, I don't have a way to measure it, I guesstimated 1 to 2" but probably more likely in the less than 1" range now that I think about it again. So, everyone else, while you are driving down the road and come across a bumpy section and see the overhead portion moving up and down, take a look in your side view mirror down this sight line and I am betting you will observe some movement as well.
A early indication you have too much weight in a El Camino is the doors won't open.
There is always a gap between cab/bed to allow for flex. Early in this thread I told what I look for with regards to frame flex. Pick a good day, put your shoulders on the ground, look the frame over. If you see no signs, worry more about the sex lives of M&Ms, less about the frame.
