I'm sorry to bash the "offroad" brand, but Jeep's Trail Rated BS is pretty much BS. They hired a private company to "trail rate" their products, with numbers equating to performance, (And the Rubicon Wrangler of course a 10...) and when said private company found the Compass and Patriot "not worthy" of a trail rated badge, (Which required a 3 out of 10 or something like that) Jeep fired them, and just started making stuff up and tossing a badge on.
I guess what I'm saying is do your homework. The "Trail Rated" KK's don't have any more ground clearance than the non-rated ones... And they have less than a Volvo... That's just sad. I pried the Trail Rated badge off my wife's KJ Liberty and stuck it on my little red wagon... In stock form it is completely lost off a graded road.
FWIW, the Volvo likely has an excellent traction control system, and at one time, at least the XC90 had a "low range" that worked fairly well. Not sure if the 70 does, but I can't see how it could be worse than a liberty.
I know, some of you love your Liberty's. That's OK. I think I still harbor some ill will toward Jeep for the first Liberty, which was released while I was there and it was a design failure in so many ways... (Over weight by 900lbs, FAR less capable offroad than a cherokee, messed up rear suspension geometry makes it fairly twitchy on the highway, less interior space than the old Cherokee, horrible seating positions and seats, at least in the Limited, and don't get me started on upside down lower balljoints...) I think they fixed a lot of stuff with the KK, so hopefully it isn't as bad as I know the KJ to be...
