I have a Range Rover (albeit the better version, Classic
) and a slabbed driveway that was done ~13 years ago. 450mm^2 ~30mm (looking back, should have gotten thicker slabs, and bigger ones at that, the larger 600mm^2 and 50mm at least. Big heavy and don't move very much) slabs layed on several tonnes of sand that was leveled and flattened etc etc. Ideally it would have been mixed with cement and then a cement and sand mix brushed into the gaps, but only sand was brushed into the gaps and its turned out okay...
Now its fine jacking up the RRC, but I always put down either 1/4" or 1/2" sheet ply that I have cut into squares. I have four, one for each axle stand if needed. Their area is bigger than that of the axle stand so the weight is spread further again.
After 13 years or so all the sand has compacted, the slabs have settled etc so its fine now and I haven't had any stability issues. But on a freshly layed blocks I'd take it extra careful.
