Welcome to the Forum!
I have a 6' tall enclosed trailer and the door opening is about 4" shorter. My Wolvie won't even come close to fitting. I ended up buying a 7' enclosed customer trailer to haul it. It' 7' tall x 7' wide by 16' long. It's a pleaseure to load/unload. Keep in mind that once you load it you still have to get out of your quad and trailer. If my trailer was any narrower I would have to crawl out over the hood.
Here's a pic of it:
