I am sorry about your loss, I have seen the "nite" scheme on a few trucks, they are a regular F150 that has the "Nite" package most are black with a pinkish stripe.
The fact that the truck is well cared for may bring more value, but seeing it is almost 10 years old the blue book value may not be that high. take care and good luck on the sale.
I have also seen a few broncos with the same trim.
