Last summer a fellow camper got his trailer stuck in the muck and the wheels were locked. He dragged the trailer out with a huge mining tractor that was available, but the wheels were all locked up. He was going to just drag his trailer with wheels locked down the road to the garage about 10 miles away. I stopped him, tried to find his break away wire, but with all the muck, it couldn't be found. So I removed the positive battery cable from the battery/ washed muck away and the wheels started to turn. He still needed garage work, but that fix did work whether it was by coincidence, not sure. He was not a happy camper still, but repair costs no doubt were much cheaper than what they could have been.
Have a coffee, break, sleep, etc before you do something drastic like the guy above was going to do. Talk to people, phone a service centre, but just getting angry and doing something dumb with an expensive trailer may cost you thousands of dollars. Oh and you should never be drinking and driving of course, but driving while sleep deprived is bad too in making decisions. I think the guy above was physically and mentally exhausted and needed sleep/ rest for sure - but oh no he had to plug on he said.
