Hey John! Yes, your Demco Autoslide # DM8550034 can be converted to fit your 2024 Ram 3500 prep package using the Replacement Side Plates for Demco Autoslide 5th Wheel Trailer Hitch # DM99GV. All you need to do is swap out the ISR adapter plates with the new side plates on your current hitch. Do you have any big summer plans with your 5th wheel?

Hey John, how did the swap to the new side plates for your Demco Autoslide go on your Ram 3500? Your update could make it easier for others looking to convert their hitch for a puck system.

Had a problem when I tried to slide my hitch into the capture plate. Problem was I did not have the opening set wide enough. Had to move the Demco side plates all of the way out and remove the big adjustment bolts from the side plates. Then I was able to access and tighten the adapter plates Allen bolts through the hole that once had the adjustment bolts. Once I got the Allen bolts tight, I replaced the adjustment bolts and everything was fine. But my plates are ALL THE WAY OUT. This is not a problem, in fact everything works perfectly. Just did not realize that I would have to move those plates all of the way out.

Since the pin weight of your camper is 2.1k, I recommend going with the LoadLifter 5000 opposed to the 7500. While technically there is not reason you couldn't use the 7500 kit, it really is not necessary for a camper like yours. Generally the…

Hey Jerry, GM moved the placement of their puck systems starting with 2020 models so you are correct that the pucks would have the hitch not sit directly over the axle. GM did the math and made sure that this placement wouldn't adversely affect…
