Didn't read through all of the replies.
I just went from a 2010 Tacoma DC to a 2012 four door JKRU. I honestly have pro's and con's with both that equal out. I miss the bed space to haul rocks, lumber, equipment, etc. in the Tacoma. But, I love the fact that I can do a simple google search to find a simple, inexpensive mod for the Jeep. Modding the Tacoma was literally going to the hardware store, building the actual mod, the applying that mod to the truck (i.e. Black HeadLight Mod, repainting dash from silver to black, different color LEDs for the dash lights). I never used the back seat in the Taco and saw it as wasted space (hated vacuuming after traveling with the dogs, so they moved to the bed of the truck).
I love the fact that in the winter I can take my JK, put the hardtop and OEM metal doors on, then spring comes around and I can comfortably drive around with the soft top and no doors. The way I have my Jeep set up, it's a traveling recovery vehicle/home away from home. I can comfortably sleep in the back with overhead protection from the elements.
...not to mention the Straight Axles...Can't go wrong there.
I loved pre-runners and before I received orders overseas, I planned to put long travel on the Tacoma. Instead, due to a bet with the wife, I sold my truck. It was a painful day, but I've fallen in love with the JK and will most likely not go back to the Taco.
But, to each his own. I say if you want to jump dunes and spend a ton of money modding out your vehicle, get a Taco. If you're happy with doing simple offroading, maybe some light rock crawling, with a comfortable place to sleep at night, go for the Jeep.
