The starboard board on the trailer is finally dropping all its rear lag bolts!!

Tied the loose item up with a rope to get it where I could put the boat
on after fishing and made it home, but now what !!

Does the boat need to be jacked up off the bunk to fix the problem or do I
need to bite the bullet and take it to a boat/trailer shop?

I'm too old to start crawling under trailers...........

Shop or Cash to a Reno helper...?
