Seems to me the flex may be a function of the weight of the person perceiving it and would likely feel flex in the center of the slide out rather than the wall edges. How sensitive a person is to flex is also to be taken into account. My trailer wobbles a bit when someone walks through the cabin after being set up. My wife and I are used to it and don't notice; it isn't much. My buddy walked through and noticed and found the wobble disturbing. The wobble is normal (hope wobble doesn't sound like it is rocking; only moving a tad). Go to an RV dealer and check out some of their units with a slide and dinette and see if you can feel flex to get an idea if your flex is normal.
