M1894 said:Jack does your exhaust system look like it has overheated in that area in the past? It might have just provided enough heat to cause further expansion of the foam in that area, causing the floor to buckle. A small hole through the floor outside of the raised area [probably inside a cabinet to keep it invisable.] should enable you to test for floor thickness and compare both areas to each other.
No. Everything looks normal. And I did cut a core sample (photo above) from the center (high point) of the hump and it is a normal thickness.
