I 81 in North Va. has a B5 Blue Section, or a Tale of Two Trailers

If the angle that trailer is sitting at is the same as when it was towing, that was likely the issue.

The Durango needed a drop hitch to level the trailer. She got the "Tail wagging the Dog" is my guess from the trailer being tongue high, not enough tongue weight.

Good to read everyone is OK. Hope the rest of the trip goes better.
