With half of the trip behind them, the Biermanns are ready to tackle the legendary Route 66. Only one problem - the RV's busted. Stranded in an abandoned parking lot, the Biermanns must pull together to survive the night...and each other.

It's off to Texas for the Biermanns, where Ariana and Brielle hope to find a dude at the dude ranch. Only one problem... there are no dudes. Meanwhile, Kim saddles up and faces her fear of horses.

When the Biermanns set out to explore the caves and culture of New Mexico, Kroy finds his true calling as a tour guide, while Kim buys up every road-side crystal she can find. But crystals only soothe Kim's nerves so much, as she reaches a breaking point over the RV's faulty air conditioning.
