Best 5th Wheel Sliding Hitch for 2018 Ram 3500 with Factory Air Suspension

Expert Reply:

For your 2018 Ram 3500 Mega Cab, I recommend the Curt Custom Fifth Wheel Installation Kit for Dodge Ram - Carbide Finish # C16430-204 which is confirmed to fit models with the air suspension.

Then for the best sliding hitch for your short bed truck, I recommend the Demco Hijacker Autoslide 5th Wheel Trailer Hitch w/ Slider # DM8550035. This hitch will automatically move to give you the clearance needed for turning.

If you prefer the manual slider, then I recommend the Curt A20 5th Wheel Trailer Hitch w/ R20 Slider - Dual Jaw - 20,000 lbs # C16541. This hitch has the best jaw design and has round tubes to make sliding easy and non-binding.

I've attached a video of each hitch to assist and both are compatible with the Curt rails that work with your air suspension. I also recommend adding the 5th wheel wiring harness # 50-97-410 to add a second 7-way to the bed of your truck for easy connection and a clean look.
