I have an 8 ft 3"x3" heavy galvanized steel trailer neck with 2" trailer coupler attached. Galvanized Boat Trailer Tongue 8' Long 3 x 3 Tubing 3/16 inch Thick. This neck is designed to replace any existing neck and extend the trailer length out, especially for boat trailer. It also has built into it the chain floor guard pre-built into it. This is a very expensive piece of galvanized steel. I am asking $195 for it.
