Timely post. Loading/hauling calves this week and just as Mr TC was getting ready to pull out with the last load, I saw a leg go through the floor. Calf immediately pulled it back and was fine but had to back up and unload them in the corral. Inspected the trailer and found another spot that was rotten but fortunately, both were right next to the side, and we were able to cover the area with a rubber pad & wedge a 2x6 over the pad, flush with the side and under the center gate as a temporary fix.
Totally our (my) fault and unacceptable. Trailer is only 6 years old and while we were initially diligent about cleaning it out, the past 4 years has been one health crisis after another for Mr TC and the trailer was at the bottom of my to-do list. Lesson learned, no more lame excuses.
