Hellwig Titan XD Rule Breaker Overland Rig - Dubbed the ‘Rule Breaker,’ this pickup was modified to be the ultimate overlander camper truck. The base vehicle is a 2016 Nissan Titan XD, equipped with a Cummins diesel engine. It’s also loaded with a custom-built Lance 650 camper. To account for the extra weight, Hellwig has installed their EZ-990 two-leaf helper springs and their “Big Wig” 2,800 lb. Air Springs.
