Good morning @Jakob T and welcome to Carnity Offroad Club! The Pajero is totally fine for this trail, but there is just one weakness: the rear bumper scoops up a lot of sand during driving in the dunes and eventually comes off.

If you however prefer to install a rear skidplate, Machinehead in Al Quoz does a fine job. @Pierre-andre Nutte also got one installed together with a front bashplate and flag holder bracket just last week on his stock Pajero.
Before entering the sand you will need to deactivate the traction control as well. In below article you can see how that's done:
