This Gooseneck is made to have an easy way to tow your big country trailer around. This is a coupler and ball that magnetize together and does pretty good at staying on even when crawling with the trailer.
You will need to cut the stub off the trailer and then clean up the hole. After that this coupler slides in and is glued in place. The ball can then be mounted in the bed after making a hole.
This is for the coupler and ball only the trailer must be purchased separately. It can be found on Amazon.
