Hi, i also have been been in touch with Honda about the same thing, We have a Jazz Sport CVT, and a Motorhome already and waiting with a tow bar. But Honda said we woudl damage the transmission if we tow with all 4 wheels on ground!
I spoke to car A Tow, they were not sure about it either. So i now have been looking for a cheap maybe 3-4 yr old Manual Jazz to take with us. By the way, which motorhome do you have.
