TyrePal TC215/B Monitor with Two External Sensors
When I was a kid my family and I used to go on these holidays in this wreck of a 1970’s caravan, we had this dodgy black and white TV that never had any signal and a radio that would only work if you hung a teaspoon off the aerial. The chemical toilet was only for number ones during the night so I have memories of running across to the toilet block in the dark with a loo roll shoved up my jumper to protect it from the rain.
