Andersen hitch doesn't suit, any other recommendations?

Any of the 3 you mentioned will do well, they're all available in appropriate weight ratings and pretty well regarded. The one thing I'll note is that the Equalizer head is not able to accommodate different weight bars so if there's a chance you'll downsize in the future keep that in mind (though honestly it's more of a consideration for those that are likely to move up in the future, I think a much smaller percentage of owners downsize significantly)
