The major (basic) difference is that a diesel is able to dump off it's air from the air bag suspension, lowering the coach considerably before leveling. Therefore, the leveling cylinders don't have as far to travel. A gas coach doesn't have the ability to lower itself so the leveling jacks are at the mercy of the height of the coach as it sits on the leaf spring suspension.
Having said that, if a site is as badly off level as you're suggesting, then regardless of diesel or gas coach, proper leveling can be very difficult if not sometime impossible.
Thanks, I was thinking the lowered DP would provide an advantage in certain cases.
