I filled in a survey for some European cycling organization (the ECF maybe?) and won a trailer- I think it is Dutch (it was a while ago) and it's one of those shopping trolley types- like a Burley Travoy. Anyway, I've never towed it behind a bicycle- I use it as a shopping trolley. Biggish wheels (as shopping trolleys go), big bag. Don't use it very often now because I tend to use my Elephant bike or- more recently- get delivery.
(I wouldn't have bought one though- prefer other trailer designs and it would have made for an expensive shopping trolley)
