SOLVED. Middle Grade book series where a family goes on a road trip and people try to kill their kids. [s]

[Egg]

A book series that I read somewhere between 2015 and 2017 in middle school.
It about a family of 4, the parents and the twins, a boy and a girl, going on a road trip across America visiting tourist traps.
They got a rental for the trip because their main car was too small to carry all of their stuff.
At these different traps the twins come across certain people and they start being followed throughout the trip and attempted to be killed by these certain people.
At some point they go to Wisconsin and get cheese.
