Demco Straight Tongue Trailer Coupler - Standard Coupler - DM12717 Review Video

The coupler I recommend for your boat trailer is the Demco Channel Tongue Trailer Coupler #12564, which fits a 3" wide channel tongue, has a 10,000 lb capacity and uses the eZ-Latch system to fit a 2" hitch ball. This will allow you…
