I had the roof bumped up on a 2011 with good results.The new top adds about a foot, and height was around 54" without.
Few other mods so far on what's still a work in progress. I was gonna get fancy with steps and such (notice the step bumper on the rear doors, but decided to go with a portable for the side door. Not much weight, 350 pound capacity, sturdy with no wobble, and just pick it up and toss it inside when not in use.
The two stepper is perfect for splitting the height up to the cargo floor. I'll be adding a couple grips once I get the "kitchen" and storage unit installed.
Six foot tall, so I still have to hunch over a bit, but I can actually walk into the thing now. Mine came with a two piece cargo wall, so I just removed the section behind the drivers seat so I'll be able to fold that forward for a bit more sleeping room. Left the passenger side cargo wall in place as it's handy for the already mounted inverter and such. Total length from the rear doors to the back of the drivers seat set all the way back is around 70 inches. Width is four feet between the wheel wells, and about 57" wall to wall.
Yes, you DO need to get creative when setting it up, but there's a lot of different options, and lots of ideas from other folk who've converted them over the years. My plan is to just use it for a weekend solo camper, so it should work fine, and I figure it'd be good for a couple if you're extremely friendly.
