I really like the Tiger concept for a Class C: Way better for offroad boondocking use (in 4X4 configuration) than even the smallest conventional Class C, but able to go anywhere that a 4X4 truck camper can while providing more comfort, convenience, and flexibility - not the least of which is having way lower to the ground steps to get into it than a truck camper. I especially feel this way about Tiger's overall concept because I do not prefer to "leave my camp behind" so as to have to come back to it whenever venturing out and about - like one has to do with towables.
