Are you sure it was the right size in the first place?
I have never heard of vinyl shrinking like this. If it did, it should come
back just
fine. After all, it's cloth backed, and it's the cloth that is actually
defining the
shape and limits, not the plastic coating itself. If the plastic shrinks, you
can see the
cloth webing all puckered up (like under ripped car seats). But pull it and
you can pull
it out to the limits of the cloth pretty easily.
It really sounds for all the world to me like the tonneau wasn't cut to the
right size in
the first place.
