Graham's back at the Motorhome and Caravan Show, the UK's largest show of the year. In this second episode from the show we catch up with Alde to see a new gadget which gives you constant hot water.. yet is lightweight and economic to run. Sounds too good to be true. We also see a new slide out system for panel vans from USA giant Lippert Components. Plus we also take a look at Caravan Finders' 360 degree virtual reality service and we catch up on tyre safety from industry expert Tim Booth.
