The Demco Autoslide 5th Wheel Hitch is made to handle big 5th wheels, toy haulers, and RVs without breaking a sweat. It’s rated for 21,000 lbs gross towing weight and 5,250 lbs vertical load, which gives you serious confidence when you’re loaded down and heading across the country. The heavy-duty steel frame with a black powder coat finish resists rust and road wear so it keeps its solid feel mile after mile.
Short-bed trucks can make tight turns nerve-wracking, but the Autoslide handles it for you. The rack-and-pinion gear system automatically gives you 14" of extra clearance for slow-speed cornering. As you turn, the hitch head glides smoothly toward the tailgate to keep your trailer clear of the cab—no pulling levers, no climbing in and out of the truck. When you straighten back out, it slides right back into position for towing.
Hooking up feels solid with the premium single-wrap jaw that fully surrounds the king pin for true 360-degree contact. That full contact cuts rattling and chucking, giving you a quieter, steadier ride compared to slide-bar jaws. A 3/4" thick steel locking bar reinforces the connection and automatically engages when the jaw closes. You get both strength and peace of mind knowing your trailer’s secure while rolling down rough highways.
The double-pivot head moves front-to-back and side-to-side to help absorb road shock and keep things steady on rough terrain. Three polyurethane dampeners take the edge off every bump—two built into the head for side motion and one underneath to cushion fore-and-aft movement. It makes long drives feel smoother and less jarring so you arrive ready to relax at camp instead of worn out from fighting trailer bounce.
Getting level is easy thanks to three hitch height settings that let you match your trailer’s pin box for proper bed rail clearance and even weight distribution. The hitch comes pre-assembled—just bolt on the side plates, set your preferred height, and pin it into industry-standard above-bed rails (sold separately). Once dialed in, you’re ready to tow with a setup that feels perfectly balanced behind the wheel.
This fifth-wheel trailer hitch is not compatible with Sidewinder or Revolution king pins. Do not use any device that changes the pivot point of your trailer's king pin with this hitch.

Thank you for the review! While I do see where a hole in the mounting bracket would make this easier to remove with your Adapter Plate # DM6333, a solid bracket in this instance is much better for strength, especially considering this hitch is designed around the universal rails for trucks.

In the description it says locking plates, sold separately, are required for the Rota-Flex Pin box that you have. Item # DM6171

I firmly believe that every fifth sold should have one of these hitches. It is a job getting it in and out of truck but I feel better knowing its not going to let my trailer damage my truck.
Do you have a question about this 5th Wheel Hitch?

After about 6000 miles the hitch developed some fore and aft movement. After another 2000 miles it seemed to be excessive with a loud clunk when stopping and starting. Yes, I do grease it as per instructions before each trip. I called Demco and told them the problem and they sent me the parts I needed at no charge since it was under warranty. Since I had the mechanical ability I disassembled, diagnosed and repaired it myself. I thought later on that I should have been compensated something for my time only because if I took it to a dealer they would have charged for labor. Just a suggestion, there needs to be an easier way to lubricate this hitch rather than removing the large pivot pin and also the large pivot bolt and greasing them by hand. Some well placed grease fittings would make this job a lot easier and cleaner, especially when on the road. Also, the hitch owner would be far more inclined to do it. Other than that the hitch has performed great and I am very happy with it. Thanks.
