I've had this nagging water leak every time it rains water enters my rig making the carpet wet. It appears to be coming in by the slideout seal that may need a small adjustment. I've noticed that on the opposite s/o that doesn't leak its quite tight against the bulb seal on the inside bottom of the coach. But on the suspect leaking s/o the bottom is about an inch from touching the bulb seal. Can someone tell me how to adjust just the left side bottom of the slideout to extent out about an inch to touch the bulb seal ?? Thanks very much,
