For those hard to reach put-ins.
Yes, lock washers on both sides is a thing but I doubt it will prevent problems for you. Plus, for another little bit of work, you could avoid major troubles. Not saying they will happen but I personally wouldn’t make that my raft trailer long term solution.Welding it is something I've considered but rates will likely be more up here in the great white north. If I go that route, do I need to disconnect the grounds on my trailer lights? For some reason I worry I'll fry them if I don't.
Is a lock washer on both sides a thing? I honestly don't know. I assumed 1 lock nut would keep it tight?
