Roadable RV? Seeking comment on Van's closing comment

As a guest host on "The green dot", Sept 6th 2017 episode starting at 28:18, they asked him what's next and Van cryptically replied "I don't know, have you ever watched the Jestons?"

He could have been just bantering about hypotheticals, but he could be saying the next RV will be road-able or maybe even hover.

Does anyone know more?

I don't think Van's style is to drop subtle hints. I've heard him say things like "How high is the sky?" or "How long is a piece of rope?" when asked open ended questions like that.

I wouldn't read anything into it, other than perhaps a gentle poke at the interviewer for asking a question like that.
