Being such a large family means tensions are general high as everyone competes for equal attention on Sister Wives, but the family could find some new close quarters bring out the worst in them.

Polygamy 'Not For' The Brown Kids?

The family, who all lives in a jam-packed house, will now pile into some RV's for a Spring Break road trip along historic Route 66 in the July 6 episode-and the pressure of being one of four wives (or one of 17 kids) will begin to make things more problematic.

Adding to what makes things tense for the family, they encounter incredibly cold weather unlike the kind they're used to, and also run into an issue when the valves on one of their RVs aren't checked.

Brown Family Opens Up About Move To Vegas

Robyn is especially unhappy with the cold weather, as Kody is forced to scold her to stop yelling in respect to their neighbors at the campground.

"Oh my gosh! NO!" she screams as she exits the RV and encounters snow.

"Shhh! We have neighbors!" Kody says.

"I don't give a s-t. Are you KIDDING Me?" she replies.

During an interview portion of the clip, Robyn explains how much she genuinely despises cold weather, leading to her outburst.

"I open the door and all of a sudden the snow just POOF! Hits me, and it's cold," she says. "And all of a sudden it's like I just turned into this crazy monster , cold does that to me."

It's not the only drama the family faces on their trip. As Kody hooks up the plumbing and water on the RVs for the night, he forgets to check the valves-and loses his temper as raw sewage starts seeping out and onto the ground.

"You guys didn't close these this morning!" he screams at his son, Hunter..

"Yes we did," Hunter replies.

Kody, who is livid, doesn't believe his son.

"I promise you, I made sure I pushed them in this morning," Hunter continues.

"Somebody's dirty joke then, pulling them out," Kody sneers as he walks away.
