A couple of weeks ago I posted about installing a MORryde reinforcement and HD hinges on the tailgate for this trailer. I don't plan to carry a large spare on the tailgate, but I do plan to carry gear there so I installed the reinforcement so the tailgate could carry anything I decided to mount there.
Since this is a camper, I'm mounting a jerry can for water. It's very simple to mount a MORryde jerry can tray on the reinforcement, all that's necessary is drilling a few holes in the back of the tray and that will give me a place to carry 5 gallons of water. I also plan to carry a small propane tank on the HD hinges - a while back I designed and built a carrier for propane tanks that bolts to either the TJ/LJ HD hinges or the JK HD hinges.
What both will look like when installed:
There's room on the tailgate for two jerry cans and it wouldn't be hard to fabricate a carrier for two cans - I'd probably start by bolting two MORryde jerry can trays together side by side.
Some thoughts about sleeping in the camper... even without a pop-up roof, there's room inside for sleeping. A sleeping platform would go just above the fridge.
The mattress and bed platform would be in two pieces; a section of both could be repositioned as a seat:
With the pop-top up, there would be enough room to stand in the back.
Storage would be in under the bed; items that get set up at the campsite, like chairs, would go in the back and be removed at the campsite to provide the sleeping/sitting room.
The fridge battery will be mounted behind the Trail Kitchen, and will be charged the same way it is charged when it's in the Jeep - by the Trail Kitchen Charging System when the engine is running (I've already got a 12v outlet for the charging system next to the trailer lighting connector near the hitch on the JKU), and since I've installed an XJ roof rack on the trailer, the same rack with the Solar Trax solar panel that I use on the Jeeps can be installed on the trailer.
Another place some storage could be built would be inside the side hatches.
I don't plan to do the full camper implementation immediately because I've got some cargo-hauling trips coming up very soon and I'll need all available space inside for that.
