When I bought a new Ford pick-up truck in the 90's, it didn't come with a rear bumper. That was an add-on. I presume because different people will want different rear bumpers (regular, towing, something else).

When I lived in the desert, I regularly saw brand pick-up trucks without tailgates, or with various specialty ones, so I assume those are also optional.

What was it like living in the desert? Where abouts was it in the world? Sounds an interesting life.
