Sure can. If you run in rain, water will get in anything that isn't sealed. Check the outside seal first and see if it is cracked or loose.Tighten the bolts holding the pipe, or if you can't,go to a shop and have someone do it. I'd recommend Camping World because some shops are $125/hr and up just to look. It can be an easy fix for you or a friend who could be more athletic and younger. I'm an old man but still do mechanic work. Put a fan back there to dry the carpet and spray it with Fabreeze to keep odor out.
