What's your experience of towing trailers? Single wheel, two wheel? What brands? What hitches? Changing hitches? Any advice really? Anyone heard of Vitelli touring trailers? Kevin at D-TEK-HPVS mentioned them as being highly rated. I've not seen much about them online. I think they're a Swiss brand since the sites are in German but I don't think they are German. I've not seen any reviews but I've not really looked far (usual first/second page on Google level of searching). Apparently they use 20" wheels (406) just like my front wheel. I'm thinking practically. My rear wheel is 26" like my partner's bike. If I get a trailer matching the wheel size to front wheel on my bike makes sense. Any advantage to a larger trailer wheel than the usual 16" ones?
