I have to get to Florida and back, and so does my boat… in one piece.
Trailers need maintenance, but no one can work on a trailer with the boat on it.
So, make a cradle out of 4x4s and 2x6s (pressure treated wood). Then tie the boat to the back of your garage, and pull the trailer out from underneath, hopefully leaving the boat atop the cradle. Worked for me. Got new tires on the trailer, even a spare which I can mount. Electrical system checked out, replaced a ground wire and a bulb, new oil for the sealed bearings. All set for the 2600 miles of driving soon to come!
