Yakima Rack & Roll Trailers While a rack system works most of the time, sometimes you just need more space. With Yakima's Rack and Roll Trailer line you can add up to 300lbs of extra gear behind your vehicle. The Rack & Roll trailers use standard Yakima load bars up to 78" so you can fit four boats, two cargo boxes, numerous bikes or a combination of all of these items. Thes best part is that this trailer only weighs 170lbs and can be quickly disassembled and stored in your garage. For neighborhoods that do not allow trailers in driveways, this is a must. Add that fact that it takes up so little space, with its independent suspension and quality construction and you have a winning combination.
