Recommended Trailer-to-Truck Clearance Dimensions for 5th Wheel Hitch  

Question:

The recommended clearance dimensions for 5th wheel towing are indicated on the diagram that I linked for you. Between the bottom of the trailer overhang and the top of the truck bed rails we suggest having no less than 5-inches of clearance to allow for trailer pitch and yaw when you're making a turn while also descending a hilly road.

You can measure your truck's bed-to-rail height to determine the correct height setting (and a compatible choice of hitch) for your specific application. The Curt Q24 hitch # C16545-16021 that fits into the Ram factory prep package offers a height range of 14- to 18-inches.

For more clearance you might consider the 25K B&W Companion hitch # BWRVK3600. Like the Curt Q24 this drops right into the factory pucks in your 3500's bed but it offers a taller stance, with a height range of 17- to 19-inches. These two hitches plus all other hitch fits for your truck are shown on the linked page. You can click on the filter for height range to select just hitches that provide the height/clearance you need.
