Oops, forgot to answer your question:

The trailer is in good/excellent condition. I replaced the tongue jack and safety chains. The rollers are all fine, and a few of them are new. The tires and wheels are good, and the surge brakes seem to work fine. A few of the fasteners and a couple of the brackets that hold the rollers have some rust. The trailer frame and axle are nearly rust-free.

The previous owner only used the trailer for winter storage, as he had his boat moored over the summer. It probably saw 20 miles over the past 3 years. Before that, I don't know.

Regards.
