I bought one of those little kit trailers, what you can get for about
350 dollars, with a 4x8' bed, for a one time use, and some little uses
aftewrads. From Harbor Freight that carries 990 pounds they say. I
only need to carry less than 100.

Assembling it today, I noticed that they depend on nuts with nylon
inserts to keep the nuts from coming all the way off. They depend on
tightening them tighlly to keep them from coming loose.

Is that enough or should I put split ring lock washers under each nut.

Or would it be better, just as good, to put jamb nuts on the bolts
that are long enough.

IIRC the instructions say in one place to check that the nuts are
tight after 100 miles, which seems like a good idea, but in another
place I think it said every 100 miles!!!!!

Thanks


Yes even if they come loose they won't vibrate off and allow
disconnection. Built a custom motorcycle when I was a kid. Would not use
anything else but those. They were also used by the original manufacturer
before I chopped it.

in another place I think it said every 100 miles!!!!!

Their lawyer assisted in instructions.
