Just my opinion here, but with a Tacoma I'd want at least a small light weight WD hitch towing that trailer. The factory tongue weight spec is 377lbs, and loaded will most likely go a lot higher than that.
I tow a 17' Casita with an FJ Cruiser, and the little Casita's tongue weight is over 400lbs. I would not be without the Andersen WD hitch towing with the FJ.
