Check your trailer hitch ball.
Hi - I was fortunate not to do severe damage to 4704 while trailing around 7/4. The ball on my trailer hitch had almost COMPLETELY loosened and was ready to come off! I was saved by a fellow traveller at a stop light who got my attention. I've trailed and sailed for years and years. I've never checked the tightness of that huge nut. Never thought I had to. We were blessed this time. I will from now on. Tom Gallagher. FS 4704
