Help! Water under the skin, delamination and damage.

I have done this repair on a previous camper. As folks have alluded, it is a big job but it can be done. I have the skills to do it but it is not fun when you want to be camping.

Be careful using silicon... it is not easily removed after put down. I would recommenced a latex caulk of sorts for any interim sealing you plan to do.

Please post pictures of your camper for us to see... it will help the very knowledgeable members better on their replies.
