In this fourth episode, we meet 63-year-old Siobhan, who had a eureka moment and decided to get a motorhome. She now lives full-time in her much-loved motorhome ‘Dora the Explorer'. We meet up with her after she's had a bit of a bump and poor Dora needs to go to the garage to get her bumper replaced. Siobhan has everything crossed that it's not an expensive a job! In Hereford, we meet Lamorna and husband G, who bought a double-decker bus two years ago and have painstakingly restored it into their new home on wheels. They want to get on the road and head for the coast, but there's one big problem — G doesn't have an HGV licence! Will he pass the test and get them on the road? Across the Atlantic, we meet Sarah and Paul, who have turned their passion for iconic Airstreams into their business. They sold everything and built a 30-acre retro motorhome resort. You can rent a pitch for your own vintage motorhome or you can hire one of theirs. One customer is Bob, who's originally from the UK. He bought his 30-foot Airstream two years ago and hasn't looked back. Resident reviewer Tomi Adebayo puts three collapsible e-bikes through their paces to see which one he thinks takes poll position! In Buckinghamshire, we meet Lucy, who runs Glamper RV and hires and sells luxury motorhomes. We meet customers Sean and Lisa, who have arrived to pick up their motorhome rental to take on their Scandinavian adventure. And we join Americans Jacqueline and Dave, who live permanently in their fifth wheel RV. They have been on the road gigging with their band The Border Hook Ups for two years and love being out in the wilderness.
