There is one prospective buyer in communication with me about the Rack, RTT Mounts, fridge slide and slide mount. If they fall through I can let you know. The Rack is disassembled but in just a few pieces. Can be installed in under an hour. The Trail Rails are a requirement per Leitner site and instructions. They may be able to tell you if others will work but the rack is attached to the rails.LAJEEPR, I see its been a few days since the last response on your rack and accessories. Do you have it for sale yet? I'm new on this forum and have been looking for a Leitner Rack. If I was to come out to buy the rack, do you have it dismantled or just set it on my Gladi for the ride home? I don't have the bed rail trail management system on mine and think the forged rack needs that for mounting correctly. eh?
