There is a video interview with Matt Roloff from New York.
In this one, Matt is asked why the show is ending. He says the Roloffs have been wanting to end the show and were looking forward to have the cameras gone because they can be a disruption. He says TLC came to them and wanted two more years, but then came back and said they could wrap it up now. Matt claims they were happy about that.
Among other things discussed, the frequently asked question among fans...How tall is Jeremy Roloff? Jeremy and Matt have previously said he's 6 foot. Some people that meet Jeremy in person say that's about right, some say it's not. The interviewer when discussing Zach being and dwarf and Jeremy not having dwarfism, she asks if Jeremy is 5'9? Matt answered "Yeah, Jeremy is 5'10 or something like that."
The host asked Matt if they were selling the ranch (or farm)? She asked like they were really selling it. Matt said they've always talked about it and didn't expect to be there for 20 years. He said they now joke that they're going to need to sell the farm just to get Jeremy and Zach to move out. Matt says that's the big challenge. Jeremy and Zach are too comfortable living on the farm. They have the big house and all their shops and rooms and their friends come and go as they please, Amy keeps the fridge stocked for them and their friends. Matt also said Jeremy has shown some interest in taking over the farm one day.
