A related question: my 2016 Hymer (Mercedes) had complete habitation and vehicle service and dampness check last July (2020). It hasn’t been used since then (due to lockdowns) and has been on the driveway on electric hookup. I’ve put the heating on overnight during very cold spells. My question is: do I need to have the habitation, vehicle and damp services done again this July or can I wait until next year? I hope to be able to travel to Spain and stay there for next winter.
