Renting a trailer for $500.00 plus the huge fuel burn may just enough to off set the cost of an open deck utility trailer.
Tarp it, but make sure it's from the bottom up as mentioned previously. Cover the bike with a flannel sheet or an old comforter before you close the tarp. It will prevent scratching of the paint.
Sell the trailer in the spring ...
