I’m not sure if you’re familiar with the “rock gulley” at LR’s Gaydon facility? Basically, it’s a pretty heinous series of massive boulders and rocks, in funnily enough a gulley. A std defender can’t get along it due to the lack of locking diffs but the D5/RRS and FFRR get down it fine, waving wheels several feet in the air, with the cross axle brake system acting like locking diffs, it’s very impressive. But, one mistake, and boy oh boy, is it going to cost you. On one demo day, a front wheel slipped of a rock, the car landed on the front bump/sill and exhaust. 4k worth of parts (inc paint) to fix according to the proto workshop (obviously it didn’t actually cost them that, but it would cost you that if it was yours). So my point was, and it applies to any modern painted sills/low plastic bumpered off roaded, that unlike a defender which you can straighten out with a hammer, for something like a RRS, the off road ability is not limited by the vehicle, but more by your wallet…… 😉
