I had the same problem with my Rockwood Fifth wheel. You have to close the slides to view the seal in the wheel well area to see if the seals the floor of the slide out with the main floor of the camper. As you travel on a wet road the wheels throw water up under the slide outs which will leak into the main floor.
Especially in the corners under the slide out in the front and rear. All the seals
in my camper had to be replaced with larger seals to stop the water.
