We saw the interior wall paneling was also soaked and rotten. 

We removed all the interior paneling and saw some damage to the front framing as well. 

The wood was rotten at the bottom and had fallen apart. There was also damage to the top of the frame where the branch had made contact. 

When we removed all the rotten material, we saw that the trailer was framed for a slide and was never completed to be a trailer without a slideout.

We framed it out to maintain a bit more structural integrity. 

With the framing complete on the side and the front, we were able to install new interior wall paneling. 

Then we installed new rigid insulation. 

And finally the new skin. 

Given the age and condition of the trailer, our customer decided that instead of seaming the fiberglass and blending the paint, he would rather install a molding over the seam and hide it behind the awning arm. 

He can camp with the peace of mind that his trailer is solid, and dry. 

He left as a happy camper, ready for his next destination.
