TPO or EPDM
Did some searching but didn't find what I was looking for. Simply put, I have to re roof my new to me 2008 Thor/Dutchman Freedom Spirit 180, due to leakage at that stupid Winegard antenna. Didn't find...

Do not get the fleece backing, any minor leak will be wicked in under the TPO and cause more rot.
The primary differences (as I see it) is the TPO does not chalk like the EPDM and results in less black streaks on side walls. Also, the TPO stays white whereas the EPDM can chalk to the point that the material shows the black underneath.
The EPDM may be easier to install due to strength/thickness but I'm only guessing on that point.
Whatever you do, install the new material on new wood decking.
