Review: Very nice coupler! - I picked this up to replace the other coupler on my Big Tex trailer (other coupler was a CURT 25330 style one). My old coupler had developed play, and through a Big Tex dealer, I confirmed this is the replacement. Easy to install, HOWEVER, for max capacity, you need to use (4) grade 8 bolts through the coupler & trailer channel. You can use just 2 long bolts, but then the coupler won't be able to reach max capacity (but should be plenty for a 1/4 ton truck like a 1500/150). Demco sells a hardware kit for this coupler for ~$25. Or, do what I did and hit up your local hardware store (Ace generally has a good selection) for some grade 8 bolts, nylock nuts, and washers. Another thing... So, the Demco hardware kit contains bolts that are about 1.75" long. These are virtually impossible to find. I would up using 2" long bolts w/ 2 washers for each bolt, which provided JUST ENOUGH space between each bolt on the inside of the coupler. This trailer is also dummy-proof to latch... Remove the pin (not included) and simply lower the coupler onto the ball on your tow vehicle. It automatically pops up, then down and locks itself into place. As long as the latch is flat against the coupler, you're good. To uncouple, flip up the latch and raiser the trailer.
Review: Heavy duty and very well built - This is was a great purchase, the coupler is very strong, well built, and bolted right in to the adjustable channel on my new to me dump trailer. I needed this in order to use the S5 Coupler lock I bought, this is the perfect combo. I also love the ease of use without the need for a locking pin and the automatic latching system makes hooking up so much easier and convenient. Slipped right on to my 2 5/16 ball with no issues as all. I liked it so much I bought a second one for my other trailer the day I got this one put on.
