Wow, I guess we have been pretty lucky so far with our beat up old trailer. But I can tell you an embarrassing moment. Coming back from a rally in Texas we stopped at a 4 way stop sign. One of those town squares that are in every small Texas town. Started to turn left, got right in the middle of the intersection, and all wheels locked up on the trailer. It would not budge. Naturally we had every lane in every direction blocked.
My wife and I got out, I am looking for worst case scenario and she goes for the obvious. She was right, the electric brake connector had deployed. Popped the little plug back into the electric connector and all was well. We could leave and the people stacked up at the stop signs could continue on their way as well. Once we got home a close inspection showed the cable that connects between the TV and the trailer had been cut and spliced a few times. It was simply too short and got caught on the Rock Guards as we rounded the corner. We have a new one now, with a longer cable.
