@Jeep or Tacoma,
I like that concept, if I were to rotate my CVT Mt. Rainier to where the fold out part went to the back of the vehicle, then you could zip up the Annex around the back of the Jeep and have your tailgate down. with your feet popping out the back. I think for that to work though, your window would not be able to open all of the way. It'd be interesting to see how that worked...
I am very interested. I just bought the tailgate conversion kit for my JKU and I'm stoked about doing the install when I get home.
Right now I have my kitchen setup in the back of the Jeep so I'm not really setup for sleeping back there, but i ordered a drawer system from ARB a while back and I'm planning on putting my fridge on that and then hooking my stove up through that, so hopefully that will leave me space to sleep on the side.
I've been debating which seat to remove, either the 40% side or the 60% side... I'll have to install my drawer to see which side it needs to go on.
