To their credit, the dealer was professional and upfront and let me know about this issue. The good news is they determined that it would be better to have the door replaced outright and have ordered a new door with the proper sized window. The bad news is that the door will take about 3 weeks to get here. That said, I will refrain from any thoughts or discussion on any "compensation" etc here as this is matter strictly between me and the dealer, and this forum is not the proper venue/outlet for these discussions.
I was presented with the option to take the trailer now so I could work on it and bring it back when the new door arrives but I don't want the hassle and the 60 mile round trip to be made multiple times so the trailer will remain there until the door is replaced.
In the meantime, I took some preview photos today while I was at the dealer and so far, I am pleased with the trailer (aside from the door.)
The large 30"x22" window in the curbside body of the trailer lets in a lot more light then I thought it would and really brightens up the interior even with the side door closed.
