If you try to find a used trailer for her, be careful! After having gone through it myself, I would definitely not recommend even considering any trailer that wasn't already set up for a 23xx DV, and even then I'd carefully measure the locations of all the strainers, pickups, transducers, etc and make sure they won't interfere with the bunks. The other option is to go with a roller-type trailer which is more adjustable, but can be quite tricky to fit "just right".
Good luck! There are a lot of guys in Australia and Europe buying boats here and then shipping them over without trailers, so if you look around carefully you can find a trailer where the Parker sitting on it was sold. That's what I ended up with.
