Steve, the first pic is the rubber seal that goes down the sidewall of slide:
Next two pics show interior of roof of slide and a white rubber strip that travels the length of roof line:
Next pic shows the rubber seal on outside wall of motor home that travels across the roof line as slide opens out.
This pic is where the bottom of slide drops down to a rubber seal that runs along the bottom of slide:
If you look to the side wall of slide you will see a reflection of sealent buildup to stop any water from entering on to floor and rug with the slide out and you peel back the sidewall rubber seal outside you will see sealent built up behind the rubber seal.
The last pic is of the interior of slide floor level that drops down flush to the floor. The bottom trim is the floor of slide that butts to the backside of dress facia of slide, it also has some sealent to block any water on top edge of trim piece to aluminum angle strip you see, the aluminum angled strip you see runs up the side of slide and seals against the rubber seal from the interior side of rubber seal you saw in first picture.
Not knowing how your slide is setup for seals these pics may help you with yours and where you can build up some sealent so you can keep out the water.
The sloped roof edge at the front of my slide you may not have, that point maybe just a 90* angle and at that point on some slides I have seen because of stress at that point the roof line of slide and facia will cause a crack in sealent at the angle point allowing water to enter.
All my seals have a edge like a wipper blade on them that wll squeegee the water off side walls and roof. My seals have metal strips on surface of seal to hold in place, they are not glued to sidewalls of coach.
My slide topper doesn't have holes in it to allow water to flow thru over the center of slide I would have that replaced to keep off the water. My toppers are four years old and look as good as new with a metal wrap. I clean them when I clean the roof of MH each spring.
One other thing the wipper portion of seals as they are now are turned inward. As the slide moves out the wipper portion of seal will fold outward and ride on surface of slide wall. At times the complete wipper of seal may not all fold outward leaving a fold in seal. That fold will allow water to get behind it and water will travel on inside of seal to your floor and rug. I will use loop end of your awning rod and run it up behind the seal so all of the seal is turned out as the rest of the seal should be which will not allow water coming off sidewall of slide in a driving rain.
