A lot of those SUVs (and Jeeps, trucks, whatever) that do get a taste of the action don't make it off-road for a long time, then purpose built/highly modified, and that done with actual intelligence nowadays. The days of a 6" or 12" lift and way stiff springs have given way to cut fenders for larger meats, compliant suspension, and beefed up or replaced axles. (tall stiff lift may still be used for mud bogs or sand dunes) Dual transfer cases for certain conditions. My first year available in the US Strange Rover has factory issue dana 60 knock-offs. Some parts even interchange, but they sadly dropped the ball and made the axle shafts out of peanut butter! Later Discovery era rovers came with stronger axles, mostly by means of a higher spline count. 90% of my off-roading was in a bone stock Jeep J-10 with off-road 31 x 10.5's.
