Slight Water Leak Problem

[PigletPastures]

Would love it hear ideas on how to fix this water issue i have.

On my soft floor CT right where the PVC base and the canvas join sometimes gets a leak in heavy rain. If the floor isn't sitting perfectly level (which is never easy to get when camping) the PVC and canvas seem to create a small fold and the water running down the outside pools there and finds a way in. The rest of the canvas seams are all nicely seasoned (thanks to the never ending summer of rain in Brisbane).. It's just in the far corners of the PVC base away from the trailer bed.

Get a tube of seam seal from a camping shop.  Put it on the inside.  Works a treat.
