Ive never installed a fifth wheel hitch but I am a diyer and a farmer, I have mechanical ability. What brackets will I need or parts to perform the install and how do i do it?

RBW hitches will typically have the same footprint as a Reese hitch so you'll want to verify the connection point spacing to ensure it would fit a standard ISR rail kit. I've attached a diagram below showing the spacing of the rails. For a 1999 Chevy Silverado 2500 you would need the Curt Custom Fifth Wheel Installation Kit for Chevy/GMC # C16418-204. These custom-fit brackets will make installation a million times easier since they'll use the factory holes in the frame instead of having you drill out a bunch of holes. I've attached an installation video below so you can get a better idea of what this would entail.
