If you absolutely want a slider, then one of the auto sliders above are likely best choice. You could get a manual slider, that you'd never use anyway, due to GM having the longest distance axle to cab. My choice for a great hitch, for the money, to put in standard bed GM, would be a non-sliding, but adjustable ahead/back B&W Patriot hitch. They do make this hitch in a much heavier, more expensive, slider version, if you don't want one of the auto'sliders. The Patriot is available in 16K, or 18K.
