Thanks for the very kind and easy to understand responses. The cycle weighs about 500-lbs. DH did not adjust the WDH for it. This is the second time we have towed with the motorcycle. I don't recall feeling so much movememt before, though. This is the first time we have towed with the new tires.
If we can find a truck stop, how do we go about weighing? Do we need to weigh the truck and trailer together? Just the trailer by itself? I assume we need to unhitch to get the tongue weight. Do the truckers get mad when you use their scales?
