G'day,
I recently made some dust covers for the fridge vents on the Goldstream.
Last week we were away and had the covers on whilst traveling (the fridge was off), but forgot to remove them when we set up camp about midday. The fridge was turned on using gas. About 7:30 I suddenly realised what I hadn't done....
Fortunately, there was no fire, but if I had left the cover on for much longer....
