Eric,
I don't know exactly what you plan to do with it, but I can explain what I got, why, and what I would have done different...
I bought a 2011 TRD Double Cab V6 Offroad package in Oct? Of 2010. It had the 5 ft bed ( which I believe is the only way the off road model comes with, the sport has the 6 ft bed) because I am 5'10" , the bed is not practical as a sleeping area. It does give me a much better departure angle though.
The 2" tow hitch is rated for about 6500lbs, but the 7 blade electrical connector is in a poor location and needs to be relocated when you can. ( mine broke my third trip out in Colorado.)
I didn't like the idea of pulling the rear apart to install a locker, so the elocker was a plus for me. The locker will only engage in 4 low, but I don't see that as an issue since I'm in 4 low anytime I would need the locker anyway. In 4 hi there is a limited slip button ( I don't remember what they call it, and it is hard to see) it engages the braking system to spread power to all wheels from what I read on it.
I did get the JBL subwoofer with upgraded stereo as I like music...all music, from Bach to DMX, and I like to hear the strings or electronica loud at times. I do however wish I would have added the iPod connection to it. I have my iPad mounted to a support stand and use it constantly as a navigation device/ media center/ Internet/ email center.
The suspension was removed within 5k miles for a Toytec system with add a leafs in back. Not that the stock one was bad, it rode very well. I just wanted to add a couple inches in hight and stiffen it up for weight that is going to be added in the form of custom bumpers, winch, and a few other goodies to add, along with tire clearance. Will upgrade those when my current ones get bald...no sense in wasting good rubber.
The engine is plenty powerful with the truck in stock form, but I keep asking myself if I should have gotten the supercharger version. I hate the idea of tweaking with an engine after purchase...bad things happen to good engines that way. When the truck is loaded , and towing a trailer, I just feel a little underpowered.
Some other things I have noticed:
The cup holders are designed for cans of soda, not the comedically oversized regular soda's from a drive thru.
The fuel sensor is mechanical, not electronic, so it is not entirely accurate, and does not update fuel in my Ultra Gauge.
You can not roll the windows down on the highway. If you think it's windy in a topless Jeep, test drive the Tacoma at 60 with all 4 windows down.
That traction control button I was talking about earlier is tucked under the air con controls, and you have to lean to your right to find it.
It is difficult to find used caps or campers for a 5 foot bed.
I don't have the visibility I was used to with my old 94 wrangler, or the 110 I drove in Iraq.
All that said, I love this truck, and don't regret the purchase one bit. It is the most capable I have ever used in stock form. I only say the negatives so you know what you are getting. I never liked reading all the positive reviews that omit the negatives.
