So it sounds like no one else can duplicate the link navigation needed to get to the coupon view that I found...
My first step was to enter the drawing.
2nd step was to view the 1500 trucks.
3rd step was to view discounts
When I viewed the information, I always went to the bottom of each browser screen, sort of looking for a button to show me my discounts.
I spent less than 10 minutes, but can't remember the exact site navigation I used.
It seemed like the last steps I did after looking at the trucks was to enter the trim and zip code from a 'view incentives' button.
If no one else can duplicate this, I will scan my printout and post as proof I got through the treasure hunt.
