I think it’s fantastically British and would definitely go on a solo camping trip in it, it would be fun desperately trying not to be overtaken by a truck on the motorway and being blown over. On second thought I’d avoid motorways I think!
I think there are people who would like the idea of a small cheap personal camper. When they get too old for bivvy bags etc they can lie in the Rialto, rocking in the wind like in a hammock under a tarp, parking it at odd angles between the roots of large trees.
