Tom I had my first Smart in Switzerland many years ago, never towed it. When we got back to the states we bought one, a 2009, and towed all over the country as described above with the front wheels on the dolly. In 2014 we got the current Smart and it to has been towed mostly in the eastern US. Covid held us back some. I did wear out one dolly but as far as any problems with the Smart we have had none. I bought in the first place as my research at the time indicated it could be towed 4 down or on a dolly, trans in neutral, ignition on, ( has to be in park to turn switch off). I said I could load it in 5 min maybe not but no more than 10. You only have to strap down 2 wheels and its done.
