A gentleman who is not active online but probably the most accomplished EV pusher EVer is currently en route to my place on his semi-annual rental property inspections from Utah to So. Cal. to B.C. Canada and back, all done with an aircooled VW engine pushing his RAV4 EV!
My second pusher trailer (and first one built from scratch by me) has recently finished engine resurrection and installation (pulled from a Karmann Ghia totalled in a 1995 collision)!
