That Hummingbird is about the same weight as my old pup. I would start with a regular weight bearing hitch, and move up to a very basic WDH if needed. You aren't going to have to transfer very much weight, so a regular inexpensive round bar or trunnion bar would be sufficient. Just make sure to get small enough bars - our Husky lightest bars are rated 400-600 lbs Tongue Weight. I think most of the really high end hitches being recommended here are probably more (and more $$) than you would need for such a small TT.
