From the videos description,

Better than an Alamo and almost as good as propane. An all new season of #KingofTheHill​ drops Aug 4th on Hulu and with #HuluOnDisneyPlus​.

After years working a propane job in Saudi Arabia to earn their retirement nest egg, Hank and Peggy Hill return to a changed Arlen, Texas to reconnect with old friends Dale, Boomhauer and Bill. Meanwhile, Bobby is living his dream as a chef in Dallas and enjoying his 20s with his former classmates Connie, Joseph and Chane.

What a wild direction Hank’s life took.

Also making Bobby’s former bully Chane Wassanasong his friend is interesting.
