The hitch battle is just like a best oil thread. Goes no where accomplishes nothing proves there is way to many opinionated people out there. All the hitches that have moving parts are a failure waiting to happen ( yes I know you have been using wonder hitch x for 30 years and no problems), the only advancement in hitches is the Andersen Ultimate or the Pullrites super light. Just to easy and no moving parts to fail. Dealers won`t push them on a new camper sale cause there is very little profit in it for them over the expensive lead weights they have on display. Manufactures will say they will void your warranty but offer no engineering facts behind the statement. I can see the smoke coming out of her ears trying to explain that one. They are truly the wave of the future but it will take time.
