Welcome to the forum Baswinfo.
I don't recall ever seeing the actual VIN # stamped anywhere on a trailer other than on the exterior/street-side.
The 6-digit # you found (in the cabinet) is likely the Serial #. That said [& thinking out-loud here] - do you have
a Keystone (or other) RV dealer nearby?... maybe they'd know if VIN #'s are hidden/stamped elsewhere. Are there any
RV dealership decals on the RV?... if so, that dealer may still have info from their sales records [using Serial #,
from the cabinet?]. Last but not least, I'd suggest contacting Keystone.
