I cannot find a Model number on any of the paperwork (I am the second owner and have all the original paperwork) - but I am pretty sure you nailed it. Says on the outside of one of the folders from the dealer - Fun Chaser 22.
I have seen a couple same year - same model and inside layout/options - on dealer websites asking $4 to $5K - but then again - they are dealers with a markup. Hopefully at that price everything has been checked out and either repaired/replaced.
I would keep the trailer if I had a place to work on it. That is my biggest problem. I cannot bring it home (Deed Restricted) and I cannot work on it where it is stored.
I will miss it. For the 5 years I got to use it - it was a great trailer!
