Toysmith Großer Kipper

My two-year-old filled this thing with rocks and it didn't even wobble — the wheels are surprisingly sturdy. The dump bed actually tips and holds a real load, which keeps him busy way longer than his other trucks.

My 4-year-old filled this thing with wet sand for two hours straight and the bed still dumps without sticking. It's bigger than I expected, which is a plus since he can actually haul a real load around the yard.

Took this to the beach and the wheels rolled fine over wet sand without sinking. The bed holds a decent amount of shells and rocks, though the dump lever is a little stiff for my four-year-old to flip on his own.
