Demco Hijacker Autoslide 5th Wheel Hitch Recommendation for 2018 Ram 3500 With Tow/Prep Package
Question:
Looking to buy your demco 18k auto slide hitch and installation rails for a 2018 ram 3500 with a 6 1/2 bed and factory prep kit

Expert Reply:
The Demco Hijacker Autoslide is available in a 18K capacity version as part # DM8550034 or in a 21K version as part # DM8550035. To install the hitch in the bed of your 2018 Ram 3500 with the factory tow/prep package, you'll need the # DM6099 rail kit. The # DM8550037 hitch you'd looked at isn't compatible with the puck system.
If you wanted to install a 7-way trailer connector/wiring harness in the bed of your truck, you can do so using part # C56000.
