I figured this would be a good subject to start, so here I am

This is my first vehicle (I'm only 17) so i'd like a little information. I know the 402 is a fairly uncommon engine and I also know the "Custom Camper" package is a little uncommon as well, but I know virtually nothing else about the other things that were ordered for this truck in terms of rarity, so could someone enlighten me? Any help will be appreciated.
