Quoted from PghPinballRescue:Costco sells a Cosco brand dolly that is convertible from dolly, to flat bed to dolly with kick-out wheels.
$80 I paid.
Get one and wonder how you lived without it.
Its even go no-flat tires, but don't leave a pin on it for extended periods of time, the wheels will develop temporary flat spots.
Is this the one fron COSTCO https://www.costco.com/Cosco-3-in-1-Hand-TruckAssisted-Hand-TruckCart-with-Flat-Free-Wheels.product.100361868.html?
How does it go on steps?
