get a covered trailer...GOOFY
I've used a lowboy and I now have a covered trailer. Two things I would add that you probably already know is use a wheel chock and add an extra tie down through front wheel to the front of trailer. If your using a lowboy, depending on your ramp length, you may have to raise the front of trailer to make sure you have enough clearance when loading the bike. I only have about 3.5 " on mine.
