Where is "level" determined on a fifth wheel?

I use the bottom frames of the basement storage openings. Wife likes it about an eighth of a bubble nose up so the bathroom door doesn't swing open and she says she sleeps better. :h These things are pretty flexible and the chances of getting the whole thing level are somewhere between slim and none. Seems to work fine, the original Dometic fridge was still going strong when we traded our 13 year old 5er in last spring.


We do most of our cooking outdoors so don't care if the range is level.
