Hi Benny. I know this response is too late (just logged in back to carnity after couple of years).
The grand cherokee WK2 is an underdog in terms of offroading but it’s a capable 4x4. I owned a WK2 as well and been using it on my outdoor trips almost every weekend. If you really use it in the dunes, it is important to get a steel skid plate that protects your sump and radiator, it’s the weakest part of this grand cherokee model. Check the guys in instagram @WK2_UAE some of them had upgrades and custom jobs available in UAE.
