When visiting my daughter in Townsville I set my aluminium teepee up in her driveway and it slopes just like that. To solve the problem I got a concrete block and a few concrete pavers from the big green shed and a car axle stand to take the towball weight of teepee. I then place the block on the ground with a paver on top then sit the stand on that and adjust until van is level. I place the stand under the Aframe not tow ball hitch and close to the teepee. Works well for me.
The concrete block I think is called a Besser Block and hollow in middle. I put block on the edge so hollow is facing up and takes the paver easier and makes stronger.
I don't rely only on the jockey wheel but do have it still lowered as well just in case needed. It also needs to raised up as well but not taking the weight of teepee.
I then just leave the block and pavers in her garage when I leave until next I visit. I usually spend winter in Townsville.
Edit...Added pics. You can get single hole as well and a thicker one too.

Should never use bricks as a support structure ( they can and do crumble), should use solid blocks of timber like short lenths of wooden railway sleepers
No way the fridge will work even when level as long as that caravan cover is fitted - absorption fridges need a free flow of air which the cover will prevent.
