I have a long list of terrible trailering stories that I won't go into here. Last summer I started wrapping the hulls from the front beam forward with stretch plastic wrap normally used in shipping. Works great, one roll cost $5, we used about half the roll last year (wrapped for 5 road trips). Keeps on the road grime and bug grime off. At the bows I use extra layers which provides a reasonable amount of protection from stone chips, very economical.

Something else I do for long distance traveling is diconnect the standing rigging from the mast and trailer with the comptip above the vehicle. After getting rear-ended last fall when I had not, I believe that will be standard procedure for me from now on.
