Just wondering about your thoughts on this.
I'm considering buying a 1996 Monaco Executive 40' Cummins M11 with an Allison 4060.
Will it hurt the coach to back it up a 15% slope for about 200 feet?

Worst problem will be at the dishes sliding to the front.

As long as you can clear the rear approach angle you should be fine. Those rear overhangs are sometimes long....

Boy, this brought back some memories ----
First - to OP - as has been said, should not be a problem once you clear the transition.
Memory -- In the OLD days - used to have to back up hills that the forward gears just could not pull ( old trucks on the ranch ).

The Allison 4060 has a higher ration in reverse (4.8) than in first (3.5) so it will have more power backing up than going forward.
This post is my opinion (free advice). It is not intended to influence anyone's judgment nor do I advocate anyone do what I propose.

If it doesn't clear the approach would steel casters be the answer?

15 degrees??? That is pretty steep!! Are you sure? If the ground raises one foot in three feet of length then you are close. That is 66 feet higher that the road level by the time you get up there.

Grade at 15% will rise 15 ft in 100 ft horizontal. Your example is about 30% grade or double the OP's stated grade.
