I have a 23' international. I don't think a ProPride is overkill by any means--just safer and easier to tow with a crew cab Tacoma. No sway problems at all.
Was less expensive and IMHO better engineered than the original Hensley design. In any case, a Hensley hitch setup is much more comfortable to tow in the wind or out with the big rigs. No lane departures from the wind.
