2009 21SS -- Bunk End Replacement Cost/Availability?

I actually have the same problem on my 2005 Trail Lite Bantam B22S. I was afraid that i was going to have to replace the door until i talked to a local mobile RV repair person who has told me its pretty easy to repair and not have to replace the whole door. I just discovered it and haven't had him take an actual hard look at it for an estimate but he says he is very familiar with it and its not that bad of a fix. We will see soon, :h
