I'm in AZ, so not much rust here, but stuff still does get rust, so not sure if the mount to body ground on the tail light housing is the issue.
Just weird it happened all of a sudden while I had this coil issue.

You're reading way too much into this problem.. And stop all the guessing. The VERY first thing to check is the tail light fuse.. Don't guess at it, nor should you just look at the fuse.. Voltage should appear on both ends of the fuse --using a test light or DVM, check for voltage on both ends of the fuse.. If voltage is present, remove the tail light bulbs and check for voltage in the socket.. If voltage is present, either a bad bulb or bad connection between the bulb and socket is the problem... If you suspect a bad ground for the bed, for testing purposes, make up a looooong jumper with alligator clips on each end, long enough to reach between the battery negative post to the light housing.. Connect one end of the jumper to the negative post and the other end to the light housing.. When you have working lights, remove one end of the jumper.. If the lights go out, you have a bad ground.. If the lights continue to work, the ground path is good to go..
