It happens to all the Georgetown's.
You can read about how to set the panel at zero or level but this is what most of us do is...
Here are a few helpful ideas.
I try to find a perfectly level campsite and use a bubble level to find a good spot. I have 2 small bubble levels next to the control panel and can easily tell how the rig looks right to left as well as front to back.
I even try to even find a high spot in the site that raises the front end up. I can tell by my 2 small bubble levels next to the control panel.
When you are satisfied I turn on the control panel and select manual mode.
I then raise the front until I feel it raise a bit enough to take the stress off the springs. I make sure I don't over raise it by watching the front to back bubble level.
When satisfied I then manually drop the rear stabilizers until I feel them raise a small amount. After this if needed I raise right or left as needed.
When done I check with the large bubble level on the floor in the center of the rig.
I wouldn't worry much about the refrigerator unless you are extremely unlevel.
I'm sure other will mention their way they do it also.
Oh and the levelers are rated at 8,000 lbs each and if you raise the front end an inch or so off the ground I wouldn't be concerned. You also can add a few pieces of wood or leveler plates under the front tires if you are really worried.
