Don't Be Tardy...

With the Littles growing up and Ariana off to college next year, Kim and Kroy plan to take the family on one last epic vacation - Biermann style. Six kids, six weeks, going coast to coast crammed into an RV - What could possibly go wrong?

The Biermanns head to Nashville, where Arianna and Brielle are single and ready to mingle in the Music City. After the Littles go hog wild in a candy store, the family takes a detour to Ohio, where Kim learns some disturbing news about her father.

Still reeling from the bombshell about Kim's dad, the Biermanns say a heartfelt goodbye to Tracey, whose son awaits her in Atlanta. Meanwhile, a visit to the St Louis Arch triggers Kim's many phobias.

Hold on to your wigs as the Biermanns come face to face with ghouls and ghosts in the most haunted house in the country. The only thing scarier for Kim? Dropping her phone in the RV toilet.

After days of stormy weather, the sun finally comes out for the Biermanns as they head to Branson, Missouri, or as Kroy calls it, "the Vegas for Littles." But the good times only last so long as the RV breaks down in the middle of nowhere.

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.

Tracey returns as the Biermanns invade Scottsdale, Arizona. Even as they go house hunting and contemplate their future away from Atlanta, Kroy must convince Kim not to call the whole trip off after another setback with the RV.

Cha-Ching! After weeks of setbacks and struggles, Kim finally reaches her happy place - Las Vegas. It's a whirlwind night of gambling and more gambling. The only thing that could possibly pull her away is the majestic view of The Grand Canyon.

The Biermann's epic coast to coast trip finally comes to an end on the sunny beaches of Los Angeles. But as they prepare to say goodbye to the RV, a visit to a psychic raises some eye opening questions about Ariana's future.

With the Biermanns back home in Atlanta, the family unpack and reflect on all the high, lows and unseen moments of their cross country road trip.
