Your profile says your trailer is a 1992 34 ft Ltd. Plastuc that is almost 30 years old is going to degrade so it is definitely due for replacement. If you can't decide which you will like most, replace it with a curtain. It is easier and less expensive than a door. Then if you don't like it, upgrade either to a food or another folding plastic door or a Nautilus retractable door from Stoett.
I am personally not a fan of the glass doors as they can shatter (rare but it does happen), the ones Airstream uses tend to sag with use and vibration and the swing can interfere with other doors. YMMD
Today is a gift, that's why they call it the present.
