looking for vin location on 1981 wilderness travel trailer

I got myself in a situation where my trailer is in a family members name and I am trying to get rid of it. They have no paperwork and are out of state and the dmv won't talk to me. They wouldn't even tell me with a picture I took which set of numbers is the vin or how long it should be?

I can do a paperless transfer but need the vin.

I was trying to google search for another similar trailer for sale or something to match up but I haven't yet and am not sure if there is a standard, etc. I just sent a picture to fleetwood, years ago they send me a pdf of my trailer layout/brochure so maybe they can help.

Anyway I have numbers/letters in this format on the tongue and was wondering if somebody might be able to tell me which series is the vin?
