Good Afternoon HTF. My wife and I were out on our first camping trip of the year this week, and noticed some spongyness in the wall right under the window of our 04 22T the one in front of the sink. We also noticed it one of the other windows on the same side as well. I am sure that i have to reseal the windows, but in fixing the wall damage, do I need to take the top off and replace all the paneling or can I just cut out the damaged sections and replace with new pieces? Thanks everyone for your help.
