Hello out there in Montgomery country. My boat trailer has a second trailer tongue with ball receiver mounted on the end right next to the regular one with which I tow the trailer. Does anybody have experience with this second trailer tongue? It looks like it will slide out further than the main trailer ball receiver. Is it just there for emergency at the launch ramp such as when you can't gain enough traction to pull the boat out or is it to be used whenever you launch or retrieve the boat? I am considering having a new trailer made of aluminum and am wondering if it is worth the expense of duplicating this second tongue configuration. Fair winds, Tom B M17 #258
