I recently redid the rear springs and added a leaf--one leaf was actually broken.
A broken leaf spring is certainly something to check for, but you bring up an interesting subject of adding another leaf per rear corner to get more lift.
Our particular garage door clearance would not allow for a taller rig, but if that opening was tall enough, I would consider adding one leaf per rear corner, or better yet, a spacer per corner. A spacer increases lift without increasing harshness of ride. Spacers are commonly used in the RV industry to level a rig that is heavier in one rear corner than the other. It makes sense to use them to increase rear ground clearance in permanent fashion.
