Class C big foot

Thanks for the information

There are folks out there, that can repair dual pane windows. They separate the panes , clean, dry, reseal! We, over the past two summers had all of ours done on our 5th wheel....at a $100.00 per window.
I not certain if the Bigfoot windows are of similar construction. I certainly hope they are repairable, as we have a Bigfoot also......though ours ( knock on wood), hasn’t shown any signs of separation!

We had ours done in Mesa, Az., Hopefully you can find someone near you to perform the work!
