Kate Plus 8?

I watched the RV episode last night - she is actually deranged isn't she, I mean she has serious problems ( and most of them her own making by the looks of things!) I used to think she was just stressed but she seems completely bonkers. What are the bets the kids won't see Ashley again 
I am so glad they've cancelled the show - not fair on the kids and it'll stop people like me tuning in and tutting!
