Forty-five gallons of capacity is stated outright here, which is more useful than a length and width when the load is mulch, laundry or beach kit. The static rating is 220 lbs and the dynamic rating - what it will carry while moving - is 132 lbs, a distinction most wagons leave out. Inside dimensions run 38 x 20 x 14 in, folding to 22 x 12 x 31.5 in for storage. The handlebar adjusts between 29 and 40 in. Seven-inch wheels and a metal frame under oxford cloth bring it to 22 lbs.
