We're the Millers (2013)

Factual error: When the Millers' RV breaks down and it gets towed by the Fitzgeralds' RV, the two are connected by a tow rope. There is no one in the Millers' RV steering or working the brakes. The RVs would crash into each other the first time the front one slows down, and the Millers' RV would not steer properly to follow the Fitzgerald's. Also, when we see in the Fitzgeralds' side mirrors, we don't see the Millers' RV being towed.

Styist: OK, what are we doing today?
David Clark: Yeah. I say, give me somethin' that says "I get up every morning at 5:30 and commute for an hour and a half to some bullshit job where my jag-off boss expects me to kiss his balls all day just so I can afford to keep my ungrateful, screaming kids decked out in Dora the Explorer shit, and my wife up to her fat ass in self-help videos, until the day I get up the courage to put a shotgun in my mouth."
Middle Aged Man: [Pointing to himself.] Right here.
David Clark: Yeah. That's it. That's the one.

Trivia: During the outtake scenes, they turn on the radio and Jason, Will, and Emma start singing along to "I'll Be There for You" (instead of "Waterfalls"). This was the theme song to the show "Friends" starring Jennifer Aniston.

Question: After they break down, and are being towed, who is driving the back RV?
