only other alternative for the laser pro park would be to have two control boxes and run two up front, then on the other control box run one wire up front to make a total of 3, and then run the other one on the back (single) for 4. However, with that big of a truck, I would highly recommend 4 diode based jammers up front. Also with the possibility of the heads being submerged in water....might risk not having anything in the rear...I currently have no protection in the rear and have never been hit from the back of the vehicle...however...it only takes just once...
