Wife and I have 2017 FE22. We don't "stabilize", but we do level. Leveling front to back and side to side are important. I assume by stabilize you want to eliminate subtle movement while you move around inside. We don't notice the subtle movement being a problem.
For leveling we use leveling blocks. We have a set for the front and a set for the back. I think it is important to support both of the tires in the dual set, thus the leveling blocks for the back. We sometimes run out of blocks, but we have always been close to level.
