What a stonking word 'infinitesimally' is! I will try and incorporate that into a conversation tomorrow. Right now it's a tad difficult to enunciate.
Agree with all the previous ^^^ above. I’ve now made some thin insulated ‘cushions’ that have magnets in and fit three to each window in the back (5X3) These in turn fit into larger cushion cases (3X5) and are just curtains when not in use as curtains. The cases of the curtain bits are cheapso made in China type stuff fitted with 20mm skrim foam wrapped in a blackout fabric envelope with the magnets sown on. Works very well at blackout and very well at minimilising condensation almost to non existency. Cab has an insulated external door and screen cover or just put up a flag or similar above the seat backs. Ozziedog,,,,,,,,,,,,experimental but looking great so far.
