RV Repair: Pop up plastic window repair, vinyl repair kits, vinyl repair kit

Question
I have a 1986 coleman pop-up.  The plastic inner window is seperating from the zipper. It is the large window on the rear of the camper.  A section of about 4" is now seperated, but it is spreading.   Is there any way to repair the section or would I have to replace the entire section of plastic?

Answer
Well i'm assuming that it was sewn on to the zipper, you may want to try sewing the area back to the zipper then apply a liquid vinyl repair kit to the area repaired.  On older units the tent is made of canvas which is harder to work with than the newer vinyl tents but with some paitence it think it can be done.  Vinyl repair kits can bebought at any hardware store or RV dealer.
