I always dump the air before starting the levelling process and still get lots of creaking, groaning and the occasional small bang(binding).

The issue is that the levelling jacks move straight up and down where as the suspension moves in an arc (pivot point is in front of the axles, air bags are behind) so unless your coach is parked on a surface where the coach is level before lowering the jacks (so the jacks only stabilize not adjust height) you will get some noises.
