So the Family Truckster seems to be running out of space just in time for Christmas... I'm contemplating a hitch cargo rack..with a box and crap. So the Truckster is almost exactly 60" wide. The racks come in 48" and 60" in width. Would ya go big or smaller? I worry about sandblasting and weather blasting if bits of the rack and boxes etc are out in the windstream much. Anyone have any insights??
