2016 / 2017 Mobile Suites 40KSSB4 floor

[rebel]

Has anyone had problems with the 2016 / 2017 40KSSB4 floor at the foot of the bed. Floor flexing in a 3 foot area, feels spongy. If so what did you find the problem to be. Was it the frame or the 5/8" wood. Since New - I have taken my shoes off. I then moved my foot along the carpet until I felt a dip in the floor. I then tapped the heal of my foot on the area that dipped (hollow sound). Then preceded to move to another area away from the effected area and tapped the heal of my foot on that area (solid sound). Also as you walk into the bedroom it also gives way at the base of the bed box. The rest of the RV floor is sold as a rock.
