Marianne and Chris Fisher swapped their five-bedroom family house in Shropshire for Trudy the camper van back in 2018. This is not a holiday, but a complete change in lifestyle - the married couple are aiming to step foot in every country in the world. But plans have been somewhat altered by a global pandemic. Multi Story is presented and produced by Becca Bryers. With thanks to BBC Radio Shropshire. You can follow Chris and Marianne's adventures at treadtheglobe.com
