Ok. Here is day 1. I knew there was going to be a bit of water damage but I wasn't exactly sure just yet of how much. The first thing I did was tear off the sheet metal. It is put together in sections so I just undid everything holding it on... uh huh...
1. Unscrew water catch thing - no problem
2. Pull very small very rusty nails from sheet metal / woodwork
3. Pull small staples from sheet metal / woodwork
4. Work way from bottom up
Ya... it was a bit rougher than I thought but it wasn't that big of a deal.
Here is everything pulled off for the day. By the looks of the damage, I will be replacing almost all wood in the trailer. As far as I can tell, the floor seems to be in good shape so I don't have any plans yet to replace that.

Here is the passenger side front. You can see how it is put together in many pieces and then held together with a type of staple... no thank you. I plan to replace all of this with one sheet to help with the integrity of the trailer.

This only looks so nice because my amazing wife cleaned it up real well. Its one of the few things I plan on leaving in place throughout this whole thing.

This is the back drivers side. Like I said, it all needs replaced....
