Any recommendations for bicycle trailer for cargo hauling? I want to be able to haul the occasional home improvement stuff like a few bags of concrete, take trash cans of yard waste to the town skiff or get groceries in bulk, stuff that requires a hefty trailer. Don't want something huge and unwieldy sitting around though either. Has anyone invested in something they think works great for this stuff? Anyone laid down the money for a bikesatwork trailer and regretted it? Thanks in advance for your experience based opinions.
