Recommended Underbed 5th Wheel Towing Kit for 2021 GMC Sierra 2500 Short Bed without OEM Pucks

Expert Reply:

I may have a solution for you, but there are currently no OEM style prep package kits available for your 2021 GMC Sierra 2500. Since you would likely need a hitch that has legs designed for the newer GMC prep package anyways, if you don't already own one, you might want to consider the B&W Turnoverball System # BWGNRK1020-5W. The Turnoverball system will give you the same clean truck bed that you would get with the GMC OEM prep package.

The hitch you would need to work with the Turnoverball system is the B&W Companion Slider hitch # BWRVK3400-5W, which fits in the gooseneck hitch on the Turnoverball and provides you with one of our most popular hitches that's well known for its durability. The Companion has a 1" thick dual jaw that provides great security and less rattling, plus the fully articulating hitch head helps reduce chucking. This would be the best solution for your new 2021 GMC Sierrra 2500 without the OEM Prep package.
