Got my fully tinned wire for my trailer and put it on so now I have
trailer lights again. However while doing it, I found that all of the
bolts and nuts on the trailer are so badly corroded they will not last
another season. I probably need about $100 of stainless hardware to
replace them. I thought EZ Loader was quality but it isn't. What
would a bit of stainless or hot dipped galv bolts have cost them?

When I worked on cop cars, they had flexible cable that went from frame
piece, to frame piece, and from suspension to frame pieces like the A-
Frame and knuckles, rear end, etc... This was to ground the whole thing
and to help with radio disturbances due to bad grounds and connections
etc..
