Gordon, where did you purchase these from ?
I've had no luck in finding a supplier for my Merc Sprinter based Hymer 680, I would have thought that these would have been easy to source.
I did contact one UK supplier (name lost in the memory fog) who told me that their workshop had a fire and all patterns went up in flames !
I've just spent the winter living in the van (here in the UK) and while it didn't get too cold, a set of external screens would have helped.
Thanks,
james
