Hey Randy, unlike the PullRite fifth wheel hitches the Demco Autoslides like the part # DM79GV that you referenced do not require capture plates. These attach directly to the pin box by clamping to the sides. This would be compatible with your Alliance Avenue All Access 23ML. Does your camper have a cushioned pin box?

Thanks for the response. I don't know about the pin box yet. I have requested the hitch/king pin information from the camper salesman.

@RandyS Let me know when you hear what it is. It's most likely fine though.

@JamesonC Instead of waiting on the salesman to return info, I went to Alliance website and found the User Guide for the Alliance Avenue All Access models and found: Alliance fifth wheel trailers are shipped standard with a conventional fifth wheel pin box. All documentation on hitching, unhitching, etc., relate to the use of these pin boxes. CURT Rota-Flex Pin box The listing from eTrailer website shows that Rota Flex does require a locking plate: Application Application: 2020 and newer Chevrolet and GMC trucks with factory-installed towing prep package Designed for use on: 6-1/2' truck beds Fits standard pin boxes: 12" - 14" wide Locking plates (sold separately) are required for use with: Glide Ride, Mor Ryde, Trailair Tri Glide, Trailair Flexair, Rota Flex, Lippert Road Armor, and 5th Airborne pin boxes. If I find anything different from the salesman I will forward to you.

@RandyS Glad we figured that out! Since it's a Rota Flex the correct capture plate would be the part # DM6171.

There are two Demco Autoslide 5th wheel hitches that have the side plates that mount in the GM factory puck system. These work with the Silverado's and Sierra's made after the 2020 model year. I have listed both options below: 18,000 lbs…

The OEM prep package consists of 4 "pucks" in the bed of the truck that will allow you to drop in puck style hitches for easy installation and removal, that gives you a completely clear bed when not in use. The B&W Companion OEM 5th…

Answer 4

You will have to go with a sliding hitch to allow the trailer to make tight turns. For a trailer 8 feet wide the only bed length that's going to allow 90 degree turns without a slider is a stationary hitch. That being said you have two options.…

Since we don't carry the PullRite line I can't really speak to their quality but from what I can see from there website their 2900 model is fairly similar to the Demco Autoslide 5th Wheel Hitch w/ Slider #DM89GV. Both hitches offer 14"…
