Unlike Gary, I'm a big proponent of my beavertail 20' 10K trailer. I have the front mounted 10K spring jack, the ramps fit nicely underneath the trailer, the frame is sprayed with Line-X coating (no rust, scratches, or gauges there), the deck is treated, and with the ramp stands in the back, I can backup and on without causing movement or problems.
The price was right, too, so I couldn't complain. This trailer was made by ABU and sold to me through a fellow I met at the Minnesota State Fair who sells trailers in Fergus Falls, MN. I have attached a picture - the difference is mine is Line-X coated and therefore the fenders look a bit different.
Good luck!
