Continuity mistake: At home, before leaving for the Grand Canyon, the trailer was much taller than the car, and looked more like a motor home. After that, it becomes a different vehicle more like a trailer, about the same height as the car. When the prosecutor steals the car, it's the tall version, and when they arrive at the Grand Canyon to look at the view, there's nothing attached to the car bumper. When they leave the Grand Canyon it's the shorter version, back to being a trailer.

Question: Would someone please explain to me why Marcia did not just simply remove her dangly bracelet that endangered the girls standing in the house of cards competition after Carol said "Oh Marcia, Marcia, your bracelet"? It would have made it less stressful on her not to mention her team, and she wouldn't have had to restrain it with her other hand.
Answer: There were several episodes throughout the run of the show where Marcia was infatuated with a guy she went to school with. This bracelet could have been a gift from her then-boyfriend; as such, she would not want to take it off, as a sign of loyalty. A stupid thing to do, of course, but it's not a mistake for a character simply to be dumb.
Answer: The dangling bracelet was used for dramatic purposes - to keep the audience on edge.
