Following this same theme.. I was following a small trailer along a San Diego Freeway the other day. As you may know we've has a long rain spell and some large pot holes have appeared in our road system.
The trailer was over loaded with gravel and every time the trailer hit a pot hole I could see the left wheel and axel bend and getting closer to the cargo box. As luck would have it, the driver hit one pot hole too many and the axel bent to it's final position against the cargo box and blew the tire..luckily the driver was in the outside lane and was able to pull to the side of the road safely.
I guess the point is.. Some trailers are not meant to carry a lot of weight .
Did I mention that it looked like a harbor freight trailer with the small tires?
Good luck
