Is the motor/tranny out? She looks a little nose high to me?
For a drop, I think I'm going to go with a 3.5/5 drop. That should give me about 1" tire/fender clearance (measuring/looking straight on at that wheel/fender.) Currently, my truck has ~4.5" front clearance and ~6" rear clearance.
Truck looks good, nice rim choice, and welcome to the board
