Heated underbelly, tanks etc- where does it come from? Exit?

[Davidandkim]

I have the chloroplast bottom off the trailer at the moment (Victron installation).

I have seen for years the 'four season' Grand Design ad.

I haven't got the complete view, but can anyone tell me where the heat comes from? Where it exits? I'm guessing it comes off the furnace somehow, somewhere

Thanks

One of the ducts leaving the furnace is ducted into the belly

Depends what brand you own....some are simple ducts off the furnace, others are ducts and heat pads on tanks.

Thanks! Leaving winter here in a month, and it might be cold until we get south
