Hi all, We are motorhome novices, and have no option but to go to Europe in July and August. I am getting nervous as I keeps seeing advice to avoid! We can't afford Air-con (have it in cab) so I am a little worried. What will it be like inside the van? Will it be like a greenhouse? It is a Rollerteam 746, so has a summer fan on the diesel heater. I have no idea how effective this would be. Is it worth investing a few hundred in a portable air con, or a Dyson fan thing? How can I tell if they will run off a Campsite EHU? Has anyone experience of this? Can I run the engine to run cab air-con in emergencies, or is this pointless? Whilst I want to get acclimatised to the heat, it would be a disaster if it ruins our trip. Any advice?
