Builder Offering Hydronic Heat?

Thanks all. I was just wondering if manufacturers had started offering this as an option. I'm familiar with a couple of custom and semi-custom builders but anything with 6 digits in the sales price puts it out of my league. We currently have a catalytic heater in our Montana and it does a pretty good job replacing electric heaters when dry camping. We're about a year away from going from weekenders to long timers and plan on retiring our current trailer so I'm in that exciting phase of trying to spec out our next one. Anybody have a clue where I can get everything in one trailer . . . for under $10,000 . . .

:R
