If you found the source of the leak and you need to repair it an replace the sealant, you should remove all existing sealant, clean the area with Alcohol and reseal with the sealant made for your rig. (could be Dichor Self Leveling, Proflex, Hengs 311 or another) but others with the same model you have will chime in.
You should check all the outside sealants once a year for cracks leaks
