This is the triathlon of massive vehicles. After your briefing, you'll start off at the wheel of a hi-view jeep to warm up, before taking a British-spec monster truck over some tough, purpose-built terrain. You'll also get to experience a deliberate sideways roll-over in a 4x4 buggy. Then it's the bit you've been waiting for - you'll need a stepladder to get into the cab of the full-spec, 66-inch terra-tyred American monster truck. When you're ready, you'll drive this amazing vehicle over the top of two saloon cars (they'll be well and truly wrecked). Steering this 7.5 litre truck on a mission of destruction is a pure adrenaline rush. You will also receive a laminated certificate with a photo of the American monster as a memento to show your friends.
