Who would buy this? If you need nitrous on your Rhino you probably bought the wrong machine to start... you gotta have a really built up rhino to safely use a decent sized nitrous shot anyways, they're just too unstable stock.
In huevos 8 they had one of the Rhinocraft Rhinos and were running the crap out of it. They were doing this tabletop over and over again, and the one time they did it, it landed nose-heavy on the bumper and flipped. I wouldn't want to be the one strapped in that seat when one starts cartwheeling. Just the amount of money that can get wrapped into one of those things is insane.
