Selling a trailer with water damage

I would definitely point out the water damage, as to avoid any kind of legal action. The sad thing is that the damage appeared to have been caused by some poor craftsmanship at the now defunct Extreme RV plant in Caldwell, Idaho. The corner trim that seals the metal siding corners had a couple of screws WAY overtorqued during assembly (up near the top of the front corner) So much so that the screws countersunk below the moulding, and consequently, any water than rolled down the trim trickled into the countersunk cavity..and into the wall. Of course I didn't see it until I pulled the vinyl screw cover strip off the moulding.

I'm leaning towards asking $3500 and go from there.

Thanks guys!
