Ok, so in Norfolk Va, yesterday it rained 5.5 inches in one hour. I did not have the rover out instead was driving the Bmer, bad call, in hindsight. I have been considering a Mantec under bumper and have a question regarding the large center hole (is this for winch application). I understand the upper vent arrays, but I am concerned the large center hole may allow too much water intake (that is too quickly), vs the stock. Thoughts... Jon
