A couple suggestions. I have used my BoB across the U.S. (southern tier) and on several shorter tours. Keep your load as low and toward the rear as possible and you shouldn't have the high-speed problems mentioned. Also, torque the pivot rod as suggested. This will pre-load the long rod and put some resistance in the trailer's ability to become squirley. As far as the elevation goes, it's more about software (you) than it is about hardware. Make sure you have good, low touring gearing and you should be okay. Enjoy and smell the roses.
