Can I get a HOT TUB?! Well you can definitely get a HOT TUB Dolly! Full oak construction with rounded edges, but the beef of this patty is in the 10″ pneumatic casters which hold over 2500 lbs in overall weight capacity. This dolly might be called a Hot Tub Dolly, but it can be used to transport many large items across rocky areas like grass and gravel.
