Last Wednesday I pulled the boat out of the locker for first trip of the year and, I definitely had a brake locked up on at least one of the tires. Luckily, the locker premise is also a dealership, so I had instant access to a mechanic. The mechanic jacked up the trailer on each side, one side at a time, and learned that all 4 tires were locked. So he guessed that there might be a problem with my trailer’s master cylinder. The woman who runs the service department advised that I just leave the boat there in the garages and they’d look into it further.
She called back today, and told me that everyday since I left it, someone has moved that trailer around (probably by tractor with a hitch on the nose). And no one has been able to get the problem to repeat.
They’re now wondering if it might be something with my RV plug. Is this possible? When I go out there this afternoon, what sort of diagnostics would be a good idea?
