Hey Shane! What kind of 5th wheel do you have? For your 2020 GMC Sierra 2500 I recommend the Demco Autoslide 5th Wheel Hitch # DM24KV. As the name implies, this is an auto sliding hitch which will get you an extra 14" of clearance for tight turns. The Autoslide has a single-piece wraparound jaw for a secure connection and a locking bar for added security on top of that. This version comes with ISR above bed rails. It is also available with underbed rails # DM88AV if you would rather maintain full access to your truck bed like the factory prep package.
