ISO BA Tiger Wall 3 Rainfly

I am in search of a rainfly for my Big Agnes Tiger wall 3 tent. I bought at an REI garage sale 2 years ago. It didn't come with a rainfly. I have contacted Big Agnes and they can't help me out. Tiger Wall is being update for 2021 and they are not receiving any older models. Any suggestions on how I can get a rainfly? Or possibly make one? Thanks in advance :)

If you can’t find one, somehow, you could potentially get a big-sh tarp. Maybe one of those winter-wonderland type tarps that have doors. You could have a palace between your tent and your tarp.

Didn't think of that. Thanks for the idea Pringles :)

You’re welcome. :-)
