uneven and dimpled floor due to poor construction ?

Question

My motorhome , a 2006 National SurfSide 30ft classA, has linoleum floor covering. It has developed what appears to be dimples and slight dips in the linoleum. The dips are between the side to side joists. The joists are stable. They are more numerous in the traffic areas. There have been no leaks. I remember reading somewhere that the Styrofoam and cheap flooring can compress.
Anyone else having this problem?

Based on your description it sounds exactly like your floor "sandwich" has compressed, and is from improper installation or poor materials.

I have seen the Nationals being built and I don't remember any Styrofoam being used. I remember the flooring being placed directly on a plywood floor. If there are seams in the plywood, you will get dips in the seams

Yes it is probably the seams between the plywood. On our Vilano it is a 1 piece floor. Went to the factory and they have a stack of 10' x 40' treated ABS for the floor.
