I re-tightened all the bolts in the bed. Yes, they were all loose. I'm lucky the bed didn't come off (not really possible). I have four large straps on the corners holding the bed on in addition to the home made u-bolts. So the rear, which was loose, allowed the back of the bed to bounce when I hit a bump.
I will have to revisit my flatbed mount scheme.
No load on the bed, I would suspect the wood drying out as opposed to bolt stretch. I am using much the same set up and have had to draw down on my bolts a bit. The stringers I used had been cut and in the dry for about six months prior to installation on Blue. Note to self: Check bolts again tomorrow.
