Although I generally try for the center circle in the bull's eye level as I move it around the Dometic freezer floor (the freezer floor itself is not perfectly flat), I do recall the manual stating the RV should level enough to be comfortable to use, so the work needed to level to the center of that bull's eye in an oblique-angled site probably is unnecessary, and leveling to the outer ring of the bull's eye may be sufficient. That said, one refer tech once said that ANY slightly off-level operation of any absorption refer was like slow cholesterol build-up in your arteries over time, so best to always level as best one can if parked for more than a few minutes.
And how to level? We also have Lynx, and planks per this post from awhile back:
"For the 2x8 or 2x10s needed to fully support tire tread, redwood works well as it doesn't quickly split. For 4", regular Douglas fir is OK. A chain saw makes a nice rough angled cut for tire grip, but there are limits to how high a pyramid you want to stack, and they do take up a lot of room in back of the Roadtrek."
