Sleeping in, versus out of the Jeep from my experiences
Omar Branston (sp?) has some great pictures of how his JKU is setup to sleep in the back. He can even watch movies while chilling out back there.
I/m about 5'-11" depending on the time of day, and have the Jeep setup to sleep in the back with an air mattress on a raised floor. I think you'll find the fridge is plenty quiet, and may not even turn on during the night due to the cooler temps.
What I like about sleeping in the Jeep:
1). Security
2). Auto start on the key fob with the heater turned max hot, for those really cold mornings
3). The view is better
4). The speed of setting up and breaking down camp (although my buddy with his roof top tent is just as fast)
5). Wind, rain, snow, etc. makes no difference to comfort and security.
6). Built in radio, lighting, power port for laptop
7). No bumps or rocks poking me in the back, in the middle of the night
What I like better about setting up a tent
1). Room inside
2). Ease of getting in and out (for those inevitable bathroom runs in the middle of the night
3). No getting kicked out for eating cookies while in the sleeping bag.
4). Did I mention room inside?
First picture shows rocks under rear tires to level Jeep for "maximum comfort". :elkgrin:
Second picture shows raised platform for sleeping. When the driver's seat is all the way forward and tilted max forward, there is more than enough room for a twin sized air mattress. If the fridge wasn't so tall, it could sleep two people fairly comfortable on a full size air matress.
Picture three, four. and five. The raised floor allows loading everything underneath, so there is no "unloading" needed to make room in the back. This also gives Super-Mutt the entire rear of the Jeep to move around, and lie down in during travel.
Hope this is helpful.
