My current rig pulls great, and is quite smooth most of the time.  However, there is a stretch of freeway that I drive frequently, while pulling the boat, that will start doing this at about 63 mph.  It's not severe, but is very noticeable.  Also, I just took a trip down to Iowa, earlier this month, and took my boat for the first time.  There was a stretch of about 15 miles, that did this very severely, if I went over 52 mph.  No issues anywhere else on the whole trip.  I believe there can be a harmonizing of speed, expansion joint spacing, and axle spacing that can occur, that causes a serious front to back "bucking."[/QUOTE]

I believe this is the spacing of axles. If this is happening on particular stretches of road, at particular speeds, and it is a front to back bucking. I first encountered this many years ago with a Jeep CJ, no trailer. On a certain stretch of new freeway, if you went over about 50 mph, it would buck severely, front to back. It would not do this on other roadways, or other stretches of the same road. If you drove this same stretch of road, with a vehicle that had a longer wheel base, there was no issue at any speed.
