Don't think I can actually answer your question except for the fact we know there is not many and folks tend to hang onto them.
This may be some good reading for you from the panel/burb forum..
https://www.stovebolt.com/ubbthreads/ubbthreads.php?ubb=showflat&Number=243268#Post243268I don't think there has been a 'separate" total of panels and burbs but regardless, they ARE getting harder to find. I'm currently watching one that is about 100 miles from me and is a one ton.
I also feel "some" got crushed when metal prices went up that had been in salvage yards?? I know of two parts vehicles that got crushed.
Maybe someone else has a better answer... maybe Tim, Marty, George, Cletis, or Weeds can chip in here.
