Anyone use a hitch extender? Depending on the tide I have to put a bit if my chevy colorado in the saltwater which I'm not a fan of. I have a dual axle trailer that sits level on its own so there is no tongue weight to worry about. I have a class 3 hitch that is rated for 4000 lbs gvw. From what I read an extender cuts the tow rating in half so I would be over the rating for towing my boat by 1000 lbs or so. Anyone else have this situation? It would be a pita but I guess I could add the extender just prior to launch and haul out.
