Leveling coach

[ttikalsky]

I want to verify the leveling bubbles are accurate in my coach. The
leveling bubbles are located on the front dash. I believe that there
may be some flex in the coach at 40 feet in length. So today I leveled
the coach with the built-in bubbles then using a 12" level tried
various places throughout the coach. I tried the counter tops but then
the thought occurred that they may not be level so liquids flow toward
the sink if spilled. I set the level on the floor in several locations
and the readings were fairly consistent but not level. So the question
is what is the best way to verify the coach is level? Use the front
and rear bumpers or the interior floor nearest the refrigerator or?
