If you can't afford to stay in a Hotel I suppose its somewhere to keep the frame tent, dog and portable loo. But in reality I think your pushing the envelope. I think I'd get sick of having to prove that its really okay, and still great fun!
Actually saw one on the road today. Did look strange as bike had slight lean on but trailer was flat.
I poster this once before, We were in France doing in the 90s .... Got passed by a bloody lunatic pulling a big trailer with a Wing!
Saw this in Hunstanton today. By the look of it they just attach to the rear axle, so can fit pretty much any bike.
