Viper-dude, So if I am thinking this correctly, you want to have either two dually's mounted, both amber or a 6" or 8" single LED in amber in the fog openings and then a 4" white spot dually in the lower grill (on either side of the front plate)? I don't see the point in that, but it's definitely do-able.
For the AUX config with my old truck (I don't have any aux lighting in the new Screw yet), it was the following:
AUX 1: 40"
AUX 2: 20"
AUX 3: White Dually's
AUX 4: Amber Dually's
RIGID makes a "front-plate kit" so to say as I said above... They use a 4" dually on each side of the front plate.
I still recommend the normal bumper opening Dually kit. Definitely more than enough light as my pictures show.
