Anybody have any experience with tri-bar hitches? The boats and snowmobile trailer that I tow (most often things that I tow) take a 1 7/8" ball. However, many trailers require a 2" ball and I know for a fact that within the next 8 months and possibly within the next two months, I will be towing a trailer with a 2" ball. Better to get a regular hitch bar and two separate balls and just change em over then I need too or better to go with the tri-bar where all I have to do is rotate it to the ball size that I need? I've never used a tri-bar hitch where the three balls are just welded on. The one I've been looking at has decent load ratings (3,500 lbs. 6,000 lbs. 10,000 lbs. Gross Trailer Weight on a 1 7/8", 2" and 2 5/16" respectively) Any tips?
