OK, OK, I know this is campervans and not motorhomes but I think the general principle applies across both types...
The above news item appears in the latest issue of Campervan magazine. I am very dubious about the results posted. In my broad reading of campervan AND motorhome forums/groups etc, and attending various events etc I think that the 75.5% of existing campervan owners claimed to be planning to switch by 2030 is simply not the case. I suspect that Campervanco's survey went out to their own customer base or target audience. Given that they're a specialist 'eco campervan converter', it would make sense that their customers would be interested in e-campers. They reckon that 20% of their poll respondents will change to an all-e-camper by the end of next year. I think that for the very concerns they quote in the last paragraph, especially cost to change and all the issues around charging, if this survey were to run across a wide range of campervan/motorhome owners (maybe as part of the registration for a large and not 'eco' event), the results would be very different.
I'm not ignoring e-campers. A local converter has been building fully 'e' campers for some time and they're interesting to watch in terms of development. I'm also occasionally watching a chap who with his wife and child are touring Europe in an e-NV200 camper. The posts are interesting but the charging hassle and time makes me edgy even watching on YouTube.
