Never heard the kittly liter idea, I would go with a Dri-Z-Aire
. I don't think kitty litter was designed to remove moisture from air and I just don't like the smell of it. Makes it smell like you have a cat even though you dont.
Yes close the blinds, keep the sun and UV off the interior. If the LCD is easily removable then take it out. We use our smaller one in the house during the winter and when we aren't using the RV. This would necessitate taking the remote with you too. However most electronics should be just fine in the cold I am unsure about damage to LCD or Plasma screens in really cold temperatures. Best to check with the manufacutrer of the TV for the recommended low and high tempertures for the item.
