Just figured out my rails are made by Valley Industries, found a "Valley" stamped on them. So with so many companies owning others what brands fit on these rails?? I saw one place said Vally is the same as Husky. A sales guy at an rv place said he though Reese, Drawtite and Husky were all interchangeable?? Currently I have a goose setup which is why I have the rails. I just bought a 24' Terry 5th wheel and they are going to give me the hitch just they wondered what kind of rails I had. Doing some homework on my own. Thanks a bunch!!!
Go to any of the hitch web sites and look at the installation instructions for measurements. See if they match how yours are installed. If they measure up, you're good to go with that manufacturer's hitch. If they are installed in the "standard" location, all the hitches you mentioned will work. I've used Reese and Valley in the same rails.
