Re: New overland 4x4 should something be covering these wires underneath?
I think you are being overly critical; I don't see much to be concerned about. Take a peak at some of the pickups on the road and you can usually see fuel lines and wiring harnesses in plain sight. Also, with the exhaust and the suspension arms in the way, what kind of laser guided rock or branch are you expecting to come in at the perfect angle with enough force to actually damage those wires? I don't even think the factory skid plates even cover that area.
If it really is concerning, you can always have something custom fabricated to protect these areas.
