Like MisterT I would like to hear of an actual bad experience and the circumstances surrounding it.
As far as things being stressed when the wheels are off the ground, where is the proof? If a tire and rim is being removed from the coach for repairs is anything being stressed? Do you think the designers of these vehicles have not designed the equipment to handle these situations? If you were the designer would you have omitted including these situations in the design?
I witnessed an issue while leveling, a coach pulled in at the next site from me that was off level substantially both side to side and front to back. The driver pulled in, set the brake which is on the drive shaft on the f53 ford, he started the auto jack program and the front of the coach lifted first, the differential allowed the rear wheels to turn and pivot the coach toward the downhill side and bend the front jack mounts. That's the reason the instructions tell you to block front and back of the rear wheels.
