Anyone use car ramps to level?

Sorry, I did not post I have a 2013 Keystone Premier 31bhpr. I am going to level the site out soon. But I have been working cutting trees, getting water, sewer, etc for the past few weeks. We are going tomorrow for the weekend, so I was looking for a quick leveling solution. I had thought of using the ramps like a set of chocks. Back the back axle onto one until level then back it up a little more and put the other ramp in front of the front axle and it would settle down to level. But when I think about it that will defenitley be bad for the axles and tires because they will be on the sloping part of the ramp.

Well wood it is. Thanks for your help guys.
