Like everyone else, I cringed reading of your ordeal and my heart goes out to you for having gone through it, just so very grateful, as you are, that you are not hurt, except the heart ache of your trailer damage.
I too would encourage you to think of repairing, you seem very happy with and attached to your Trillium. How does the inside look? Based on outside damage it seems very repairable, if you don't want to tackle it by all means find a fiberglass place, possibly a boat works, and contact Reace at Escape
Trailers about getting a window. They make the Trilliums for the resurrected Trillium manufacturer in California and would have the window replacement for you. We had all the windows
in our ex-Burro replaced at a regular glass place that does auto windows
and household windows
, they did an excellent job so that is also a possibility.
Fiberglass looks awful when damaged, but is so very repairable, maybe a replacement trailer will come along, but consider researching the repair option also.
Best wishes, there is
a solution to put you back on the road!
