A friend and his wife took a pair of them up and down the N and S American continents, mostly around the world and various places in N Africa. In many tens of thousands of miles the odd thing here and there broke, but not much to halt progress. Daft things, like radiator or luggage mounts after thousands of miles of unpaved roads.
I think they still have them in the garage, but they're showing their age by now and I doubt they'll ever do that again.
