I had knee replacement last year and have difficulty getting into and out of my boat while it is on the trailer.  I am going to have the other knee replaced as soon as the first one has fully recovered.  I found these steps and was wondering if anyone has these or knows someone that does.  http://dtsinnovations.com/d_step.html  http://boattrailerguideons.com/trailer_steps1  http://boat-board.com/. and http://www.ezeestep.com/.  I would probably consider the last one, but they don't post a price so I'm leaning towards the first one.
Anyone have any input?
Thanks, Gary
