Had it custom made for my 2001 Frontier, thankfully it fit the 2012 as well. Nothing fancy. Sleeps 6 comfortably with the divider. Remove the divider and I can put mine, yours, and the neighbors in there in a pinch.
Which ones do you need and I will get them for you. The downside of this one is that it uses the bed as the enclosure and u have to turnbuckle it in. Sometimes I wish I had a smaller one that was easier to get in and out when I need to haul something during deer season lol
