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

I always put 2 6x6 blocks under the legs then lower the extenders some. I try not to have a lot of extenders out, I feel it allows more shake in camper. Keeping in mind do I need to to raise or lower the nose when I am finally in hooked. This has worked for me everywhere I have been, inclisites much worse than that.

Also, if something goes wrong with the motor it's a lot less cranking by hand to get them up.
