Depends on how many kilometers you intend to put on it on the gravel roads. Most forest service/ logging roads are littered with potholes, and spots with that washboard effect, especially on corners. That is going to be hard on a vehicle especially the lighter SUVs like an Escape, Liberty or Jeep Patriot to name a few. Start putting the kilometers on vehicles like that and they just aren't meant to take that kind of pounding on a regular basis. Not to say the 4x4 trucks are bullet proof, but the Toyotas and Nissan overtime will provide you with a reliable means of getting to those fishy spots, and a means of powering out in case you get stuck.
