This was custom ordered. Added the trailer backup camera with professional installation of factory GM part to integrate with your truck screen. Also, customized to have the door on driver side, 10k axles, extra height ( 7 feet interior), rear jacks for unloading without being hitched. Has both the heavy duty car tie downs and the side-by-side tie down spots. I've tried to avoid all spills and smells on the inside. Inside still smells new. Has an extra couple feet for the nose up front. Has interior lights and roof vent. Also, has a spare tire. Like new
