Question:

Hello, Can I bolt this flat plate to the top of the frame? What is it rated by itself? Thanks Can this product pull a trailer with just the 6 grade 5 bolts?

Curt says the Gooseneck Flat Plate # C65500 can be installed to the frame rails with a minimum of six 1/2 inch Grade 5 mounting bolts, but that would not allow the plate to meet the 30,000 lbs. GTW rating. They have not tested the plate by itself so it is not rated for a certain capacity. The strength of the gooseneck plate comes from the mounting crossbars and the frame itself, so the capacity would vary greatly depending on your installation.

The product can most likely pull a light trailer with just the 6 grade 5 bolts, but the trailer weight abilities will not be something stated by the manufacturer because of liability reasons.

That flat plate is only recommended to be installed without the underbed on a truck that has a flatbed mounted securely to the frame. The weight capacity then would be the same as the flatbed deck rating or the hitch ball itself rated for 30,000 lbs if the deck is rated higher than 30K.
