Plastic, plastic, plastic. Have a quarter mile dirt drive not always in great shape. We try to drive over any bumps and lumps slow. Over $3000 worth of front end work needed just after the 3 year warranty ran out. Has needed two major tune ups both costing over $400 a pop. Has operated well in snow. Happy with 4 wheel. Pull a two place horse trailer seldomly. Even with the bigger engine, truck is a bit under powered for towing under its own ratings. Would not purchase again.
