I spent some time pulling off the cover for the hitch wiring under the front belly. My lights had been intermittent. I cleaned up all the wire connections sprayed electrical cleaner all over, rewrapped the wires and sealed it all back up. It works great now.
So then I hitched up to pull the trailer for awhile just to keep it rolling, after it has sat for a month.
Got back and intended to do some polishing...found a few rear belly pan rivets that were loose. So I set out to drill those, and re-rivet. The rivet gun kept sticking and would not release the shaft after each pull. I spent way too much time taking it apart 4 or 5 times, then finally got the rivets in. Then I noticed some sealant missing on a vent. So I got out the gun and the gutter seal... an hour later I finally hooked up the polisher .
