Not to derail but the most common "Offence" or "Error" I see is the folks back their trailers too far back whilst loading. The trailer is often buried so deep that the bunks aren't even touching the hull when the bow is winched all the way up. They go to pull the rig out and, " OH NO IT IS CROOKED ON THE TRAILER WHAT DO WE DO NOW?" Well??? Yeah, you had it aligned in one spot. Arse wagging in the breeze, I love this stuff...Makes for some funny antics at the ramp.
