Do you mean that it feels like there is padding under the linoleum? Mine is the same way. I believe this is done so that it can stretch and shrink with the temperature changes. There was some mention of linoleum cracking in the extreme cold this last year. I am not sure if theirs was this way or not.
As for the squeaking and creaking, is it from the suspension or body of the trailer? Most of the suspensions can not be greased and will let you know about it. If it is from the body, I may be a little concerned.
