We have a sloping driveway, ... Ron makes a habit of parking our coaches, present and past onto the front blocks he created, just for the driveway, in order that it is level in the driveway. In doing this, we can open the slide, run the refrig if wanted, etc. with no ill effects.
For camping, Ron uses the orange leveling blocks...and, as Jamie stated, often there is no use for the and if so, it is minimal...1-2 ... so simple ... I am his guide when driving upon them.
Enjoy and have fun !
