Whwn we got our MH, I put a 12" torpedo level in the bottom of the fridge and used the levelling jacks to get it perfectly level in fore/aft and side-side planes.
I then stuck two small, self adhesive level indicators up near the driver's seat, where I could see them when operating the levellers. Works fine. My auto-level lifts the coach too high for DW to get in and out easily. By extending the jacks just enough to get the indicators showing level makes getting in and out much easier.
