The third axel takes a lot of weight off the tongue. This is especially nice towing behind a motorhome that has a lot of rear overhang. It also helps to stabilize the trailer and take away the sway you get running down the road. As for a tag trailer, 32 foot is not short. As for turning, never had a problem with a tri-axel. The last 3 trailers have had 3 and all future ones will as well.
