Randy and Denise are a couple from Bend, Oregon who caught the adventure travel bug in a big way. Both are experienced motorcycle tourists (recently returned from a guided tour in Colombia and Ecuador, for example). They had a Chevy 3500 with a 4 Wheel Campers Granby pop-up on a flatbed, but wanted more carrying capacity. So they designed a new flatbed for the Fuso Canter chassis.
The large box between cab and camper holds a 185 gallon auxiliary fuel tank, with room for additional storage. The truck frame was extended with a rack for spare tire and mounts for bicycles. No mention on the website about how the flatbed is mounted to the truck chassis.
