“Look at dat monster dump truck swimming in da water,” said our resident preschooler. That’s as good an introduction as any to the Sherp ATV. This Russian-made, adult-sized Tonka truck may have only 44.3 hp, but it turns on a dime, has two seats and an ample cargo area, can climb obstacles over two feet tall, and can swim with ease thanks to oversized self-inflated tires. It also has a durable polymer coating on the outside for added toughness, a 15.3 gallon fuel tank, and optional add-ons like another 15 gallon tank in the wheels, a generator, independent heater, and high-powered headlights.
