I had an '04 Cruiser for 7 yrs w/o flex issues. But CR, like other brands changed to a notched frame for greater turning angle. My new Cruiser had plenty of flex, about 1-1/2 inches, that was 1-1/2 inches of travel at the pin before the landing gear started to lift. CR and Lippert repaired mine under warranty when the unit was 6 months old.
Frames do need to flex, especially given the road and campsite conditions that RVs experience. However, the trailer body also is attached to that flexing frame and as those attachment points get wallowed out (hard to make good steel to aluminum connections), then the frame flexes even more. If you are lucky, you may just have steel or weld failures, but you may also have more difficult problems to fix.
Here is a link to my frame, while it dealt with an inadequate design change, it may be helpful. repairFrame repair
