5th Wheel Base Rail Compatibility with Curt Q24 Hitch C16245

Question:

Hi, we currently have rails from the Hitchiker Hitch Ultra 24-UK-21 set in our GMC 3500 Sierra long bed. The rails are 43inch long and set apart measuring 27inch wide. The hitch is set in the rail holes at 22. Will we need to have new holes drilled in the bed for the Curt Q24 5th Wheel Hitch or will we be able to utilize the current rails? Thank you

The Curt Q24 5th wheel hitch # C16245 will fit into any brand of industry-standard above-bed base rails, such as the Curt rails # C16418-204 that fit your Sierra 3500 long bed or any other brand of rail that looks like those in the photo I linked for you. These above-bed rails run left-to-right in the truck bed.

For a wiring harness for the truck bed you can use Curt # C56000 which is a simple plug-in installation at your existing bumper-mounted 7-way.
