My TT was just totaled over an internal flood of fresh water soaking the insulation underneath for a total of 2-3 hours. The underbelly was cut open within hours. I went to collect my belongings a few days later once I learned it was totaled and it smelled horrible. My insurance company didn't hesitate to total it. I hope yours does the right thing for you. I can't believe they suggested that repair was an option or that a service center would even consider touching it due to liability with health issues after the repair.
