Jack Stands

[Gardner Yeaw]

Gregory,
I agree that the jack stands should take the load. If they are
not in contact with the frame and the jack fails, the coach will
drop onto the stands. The inertia could far exceed the jack stands
rateing. Also, the sudden change in attitude could cause the coach
to rock to one side or the other. I wouldn't want to be under it
when that happened. Also, by putting the weight on the jack stands
you are assured of the stability before going under. And like you
said, something extra like that steel rim just in case.

Another note, jack stand pairs can be rated at 20k when actually
each is only 10k. Be sure of what yours really are.
