Thank you j-d and snowman9000! What you both said made a lot of sense and is helpful. I will measure the front and back as soon as I am on a level surface and before I try to use the levelors. Once I can do that ( I am currently at an unlevel campsite for the rest of the week) I will probably ask for help with the calculations. I think that I will probably have to manually level the coach so that the rear levelors do not lift the coach at all and then maybe I can get away with just lifting the front off the ground an inch or two on a fairly level campsite.
