Level on sloped campsites. How? Unique to 5er's

I have been on sites like the one pictured with our 36-foot 5th. A stack of 8 to 10 "leggo" blocks under each front landing gear solved the problem.

Your picture shows you are using a very short block under your landing gear. I find it hard to believe that the short stack is the max that will fit under your landing gear.
