Interesting
I have the similar non-superfloor plan and only had one curtain.
Most of my velcro buttons were missing. I think the ones on the inside bulkhead were the only ones..... and maybe one along each side. Those along the top edge of the windshield were not there (although there were holes where the screw would attach)
I called Thor Customer SVC and they dropped a handful of them in the mail to me.
They aren't just standard velcro, some sort of rigid disc.
