That's 200 that you put on it. Delivery could be a lot more. I agree bushings shouldn't wear out nearly that fast but I've had issues with plastic bushings failing very quickly on other trailers. I always upgrade to wet bolts as soon as I can on all trailers that I own. I will be doing mine over the winter while in storage.
