My Land Cruiser did have active height control - but this is for adjust the height of the vehicle not the balance. So I did see a lot of the world, just with using wood or rocks for balancing the vehicle.
My new rig has an aftermarked upgraded full
VB air suspension and it can do "autolevel" with an keypress. Each tyre suspension can move (up/down) 14cm - so the campspot can be pretty unflat. I dont have a picture who really show the ballancing well.
It brings a lot of more possibilities to wildcamp, it is more than just a nice addon. I loves too the comfort who comes with an air suspension, the lift (if required), or lowering the vehicle for highway driving.
I never would look back again, even when I did showed pretty well, that you can discover the world without
If you are using an iphone you can use the "spirit level /
Measure App" App for levelling your rig - if you know where you have a flat space in your rig.
