X2, limited ground clearance is the only issue I have driving on dirt.
Hard-pack dirt is fine if its a maintained road without unfilled potholes. If the road is wet and muddy you have to remember its not a 4x4. Don't get yourself stuck in the middle of nowhere without cell service or a sat phone.
My 'C' is a 24' model and I need to be aware of steep dips on some roads, dirt or paved. The long rear overhang behind the rear axle can sometimes drag if the conditions are steep enough, like some driveway aprons.
