So there's a secret about the folding wagons you need to look for or else you'll get burned like several of us FL divers, me included.
On the wheels, some are welded to the "SIDE" of the kart frame {quicker=cheaper}. The good ones have holes drilled thru the middle of the frame and it's 3 times as strong. If you are loaded up with tanks and gear,,,,on each curb, crack, or board walk you run the wheels over, it will stress the cheap welds and eventually crack and break. The karts with the wheel pins mounted THRU the frame and not on the side have been really good for us. I load 2 steel tanks +gear (~175lbs) and tug it over cobble stone walkway about 1000ft from my car down the charter docks and it hasn't cracked. Mine's the store brand from Academy Sports in Fla, but they all get made overseas. Just look close at the wheel attachment.
