Yes, all of it. The patriot is not a dedicated off road vehicle, it is a car based suv, with a decent ride and decent fuel economy. so you have a lot of compromises, and a very small after market support for it. BUT if it is optioned correctly, you can do 80-90% of what you could do with a stock wrangler sport. (my opinion obviously).
First and foremost. if you are serious about off roading, buy one with the freedom drive two package. you get a few things that you simply don't get with the other 4x4 system, that cannot be added later. Don't think a Freedom drive one or a front wheel drive will be as good...
The biggest lift you can find is a 2" lift, anything bigger puts too much angle on your cv joints, and will just break them.
The biggest tire you can fit is about a 30" x 9.5", you start hitting suspension parts AFTER you are lifted, before lift 28.5" x 8.5 is about it.
the FDII has a 19:1 crawl ratio, but it does not have a transfer case, it is just part of the regular transmission. so no actual low range.
in some ways the cvt is awesome off road, it doesn't have gears to shift through, it just gets the engine in the right spot for power, and gets the torque to the wheels, but I've had times where i've been trying to climb a hill and lost my momentum, and with the gas floored I wasn't going anywhere, tires were not spinning, i was stalled. I don't know if another car with a typical transmission would do the same, or if I was just cooking my cvt transmission fluid.
articulation is a huge minus... you end up often with 1 wheel in the air, and almost as often with 2 in the air. the break lock differentials are a huge plus here, and will get you though almost any obstacle, but i've found when climbing hills, sometimes the blds are not enough. I've been trying to find a locker that will fit in the rear, but so far no luck. (i've been told a chrysler 8.25" 29 spline would fit, but I'm not so sure on that and have found 0 technical info on the rear diff in a patriot other than a part number)
Now take all i've said with the fact that i off road my patriot more than just about anybody else I think. I haven't missed a month where I haven't taken it out at least once, and often more than once. You can see my pics and videos in the links in my signature. I think a FDII patriot is in a class of its own when it comes to crossovers. (they cherokee trailhawk is better, but costs 11k more than you can get a FDII patriot). But don't expect it to beat a wrangler off road. Like i said a stock FDII patriot (with decent at tires) will do about 80-90% of what a STOCK wrangler can do off road, but a wrangler has an almost endless amount of available mods to make it more capable off road.
