What makes this series so good, is how down to earth it is. It is believable. Hank's father Cotton surely was a handful, but a lot less is known about his Mom. In this episode, we see how much Hank care's for his Mom when she decides to get re-married, and sell her condo for an RV with her new husband.
While Hank worries about his Mom's choice in husbands, he quickly learns he needs to worry about his Mom more when she does more sporadic choices.
The episode deals with real issues, and it seams them together nicely in a endearing episode.
