I run the gen-set and an electric space heater, plus have rerouted the heat ducts and improved the fan motor flow so no more can be gained up front. I need heat in the back.
I love my auxiliary heater. Of course, it's the factory job, but I have looked around and found several at the following link. One specifically has through-the-floor connections, which is basically how A/S did mine. Mine puts out so much heat I have to cut it down, and I'm talking about heat in the whole 37' coach. It's located just in front of the bath under the kitchen cook top at floor level, which is not quite 2/3 of the way back. Manual doesn't tell me how many BTU it puts out, so I have no idea, but the 2-speed blower actually controls how fast the heat gets distributed. You will need a "Y" in your heater hoses at the engine, heavy-duty hose to carry and return the coolant to the heater (I'd install shut-offs on both lines at the engine to avoid a catastrophic leak inside your coach), 12v
power to run the blower, and a control valve (may come with heater) to control how much water flows through the unit (mine has a cable connected to the valve under the counter that allows me to control more or less water to the unit). A 90 degree elbow through the floor would be helpful, and a liner through the floor of an over sized hose to stop any chaffing there. I probably have missed something, but that's the basic idea. I hope this helps, at least as a starter. You might also check with your local NAPA store, but since you need the complete kit I suspect you will need something more along the line of what J.C. Whitney has. Let me know what you decide.
