Ibarcher,
Not sure exactly what your requirements are for this but I'll chime in. I have an 07 6 speed manual trans. Full time 4x4 with locking center and rear diffs. I've had it since new as I approach approx. 97k miles. Im running adjustable Donaho front coil overs at 2" with matching rear springs and shocks. She currently wears approx 33.7" Good Year MT/R's on factory steel wheels. It is a work in progress.
I also had an 02'Tacoma crew cab pre runner and loved that truck. In hind site I could have saved a fourtune and got a solid axel installed up front with a Marlin or Atlas transfer case but I need to stay on task . .
Issues; Toyota did not offer this model with a turbo diesel. I would absolutely love more gears in the transfer case. In technical (ie; off road, down hill, off camber, moderate to large obstacles, etc.) I would be verry happy with more tourqe and lower gearing options to climb or control the speed of the veh.
If your running a late model FJ with an adult size front passenger and small children in the rear then that's about max. For trips (not the regular commute'etc) If you plan to carry all your gear in the rear. I think this veh is ideal for the two front passengers but after that your pushing it. Exiting the veh from the rear seats or back of the veh. Is a pain. I even sleap in the rear of mine but it's not easy when you need to water the trees in the morning and you need to fight to just get out of the thing. Toyota did not put in a inner door Handel in the rear and you have to open the front door(s) in order to open either clam shell side door.
The rear seats do not fold flat. Though the rear seats comem with red knobs that allow you to remove the seats fairly quickly the rear seat backs still don't fold down completly.
The right front and rear passenger side blind spot can be an issue for some. Combine that with a lift and the cock pit feel of the interior that could be a deal breaker for some folks. You realy should rent and or barrow one to make up your own mind.
Equipped with passengers, armor, gear, etc. Your gonna reach max gross veh weight rather quickly so plan accordingly.
Due to; full time four wheel drive, angle of the front windshield, and weight/size of tire and armor I'm running I'm only avg. Approx 15 mpg in the mountains. Fuel range is not good (stock) for an expedition veh. In my opinion. You can def check on the fjcrusier forum for advice, ideas, motivation, etc. .
Now that I've got your attention, honestly I love driving this thing. The on and off road capabilties of this veh. is very good. The locking center and rear diffs coupled with the electronics it's equipped with are an asset. In technical terrain or combined with poor weather conditions ive been very impressed. Ive had zero mechanical issues and it hasnt left me stranded yet. It's very comfortable and handels well for what it is. Around town you can haul four life size people comfortably three smaller in the rear seats if need be. The short wheel base is great for maneuverability on and off road. The rubber floor and water resistant seats are very practical.
In closing, now that I've had some miles and time with this vehicle I think it is a bit of a compromise. Do I miss my truck, without question. Have I put the rear seats down and loaded up the back with my chain saw & fire wood (after driving to some narly location to get that fire wood). I'd just say make sure this veh fits your needs. I'm keeping mine forever. Even if I won the lotto I'd just do a diesel turbo conversion.
