I've read mixed reviews on these wagons. Have you had any problems with things like the wheels breaking off? What types of load do you put on them? I know the literature says about 1400 pound limit, but do you think that it would really handle that weight?

We've worked our cart hard, and it has needed a few repairs over the years. The spot where our handle attaches to the cart messed up, so we had to rebolt it in place, and I think we've malformed the metal a bit so that really heavy loads now make the wheels rub against the wagon. No wheels breaking off, though. We've hauled moderate loads in them --- perhaps as much as 300 pounds --- but nowhere near 1400 pounds. On the other hand, our very rough terrain is probably not what the carts were intended for. The cart handles mud and bumps pretty well, but I can tell it would be better on pavement or at least even paths.
