Sounds like dirt to me.
There are some serious high voltages inside a microwave.. now if there is some dirt build up on some of the components this can happen (Dust and such).
Now I Will caution SHARP EDGES ON METAL PARTS, HANDLE WITH CARE OF HEAVY GLOVES OR BOTH.
Now... Remove the unit from the RV to the picnic table,, Remove the outer cover... Inspect visually (Do not touch internal parts) see if you can find evidence of an arc (Chared anything)
If you see an accumulation of dust/ or whatever, blast with compressed air, don't have a compressor, buy a can of "Dry Air" from a photo department (used to clean camera lenses) and use it.... Then reassemble.
now.. i've worked on Microwaves, all the way down to working on the high voltage circuit.. But I'm not suggesting you do that.. The kind of voltages on that cap are... Impressive.
I am well aware of that because 50 years ago got a burn hole in the tip of my little finger from the high voltage rectifier in a colour TV back when I was working in a Radio & TV service shop. Probably in the 30,000 volt range? Took 30 years for the scar to eventually disappear!
