On a follow-up visit to the trailer, accompanied by one of the persons who was involved from the very beginning in the inspection, testing, and listing of the things, a few interesting things were quickly established.
First of all, this turnes out to be a trailer made in 1995 - and, as such, might not even be legal to instal in this town. Only if it was previously installed within the city limits can it be re-located.
Second, every exterior nameplate has either been removed, or liberally covered with paint - and cannot be read.
The only marking as to ampacity is on the panel, which says "service not to exceed 200 amps."
I did find the manufacturer's sticker under the kitchen sink, as had been suggested to me. This sticker made no reference to the electrical requirements of the trailer.
