That's what I used. The tires are pnuematic and invariably deflate at different rates. When loaded you know which ones aren't full quickly. They get VERY top heavy and turning can exacerbate this dramatically. More than 4 full supers on there and it'll tip if given any chance. I park nearby and haul full supers by hand. I do still use the wagon for hauling my inspection supplies and occaional empty supers. It works okay for bulky (but light) stuff.Also, the Lowes little yellow wagon works well as long as you can avoid the chuck holes...
