Whatever she actually travelled in her account in The Sun specifies that it was her pink horsebox (with or without cloaking device).
Quote from Unreality TV
She didn't actually write that though Sam. Could have been exaggerated by anyone, could have been confused if all she gave for the interview was a quick phone call, or even a family member relaying an account and just saying horse box. I find it difficult to believe after having just gave birth, and to a sick child, she then gave a long detailed interview to The Sun.
