Heartland North Trail Shower Curtain

We have a 2018 Heartland North Trail travel trailer. We bought in 2018 and the shower curtain has now become so brittle that we had to tear it out. It has a small track with little loops (smaller than a dime) that the shower curtain connects to. I have searched everywhere I can think of and can not find a replacement curtain. If anyone could point me in the right direction to find a new one, it would be greatly appreciated.
