As said above, go to manual mode and sue the left/right arrows to raise the RV until the wheels are off the ground. Pretty easy. The trick though is that the "brain" won't let the RV get too far of level left/right. You have to go up a bit on one side then a bit on the other side. Repeat as necessary. If you hit the point of too much tilt it isn't the end of the road. Just raise the opposite side some more.
