For moving household contents across Europe when your car’s not big enough. A local place near me does a very nice line in trailers at good prices, made from something called buffalo board I think. I can get a 5×3 with sides maybe 2ft high for a similar price to a Thule roof box, since I’d need roof bars as well.
Roof box pros: I can drive faster, the train/ferry will be cheaper
Trailer pros: Can fit more stuff in, will be pretty useful to have in general, less faff to fit/load.
Anyone got any idea of how a small covered trailer will affect fuel economy vs a roofbox and towbar bike rack? Bike(s) will be coming so I’ll need the rack if I go with the roofbox.
