One of the most important factors for towing over rough terrain is the location of the entry steps. If the door is close to the axle you're probably good to go but if the door is a ways away from the axle your steps MAY be endangered from uneven terrain. Stab jacks can also be damaged but something as simple as drag bars would protect them in many cases. I mention this because I often travel nfs fire roads and other back country roads with my Rockwood. It's build over the axles sol no problem with ground clearance but my rear door is too far away from axle and I've replaced my rear steps twice and in between those, straightened them several times.
Good luck / Skip
