Well, I'm dragging my feet on this and we're leaving for Florida for a one month trip on January 2, so it's time to get my rear in gear.
I moved the Teardrop into the shop to assess the water damage in the galley and it's been raining ever since, so good timing on that.
At first I thought I might get away with doing a "little" repair, but this is like washing one spot on a dirty white wall. You just can't do one spot. There's no easy fix here.
First, I let a fan dry it out for 2 days. Then I got out a scraper and some chisels. Fun times.
I had to let it sit for a week and stare and think and stare and think some more before I moved forward. I've removed all rotten and wet wood. Next steps are filling voids with Bondo or exterior wood putty, and sealing every crack and every spot where two pieces of wood meet, then painting the galley sides and floor with marine paint.
I also have to address the lower half of the hatch not making contact with the trailer when closed; There's a gap of about 1/2".
More soon -
