It'd be cool to see this with like wooden paddleboards like the old boats with the wooden spinning wheel on the back. That, but with 4 of them for wheels would be the coolest thing to see. It would probably have to be custom, but nonetheless; COOL!
I think it will work perfect if you glue a tick flat peace of plastic where the handle are and that will stop the water from going in and out where the handle are
If you leave the regular fat tires the truck comes with and you go fast enough it'll hydroplane over any body of water just don't stop it'll sink to the bottom
