We have the same 2001 Dynasty and replaced both Dometic 13,500 with 15,000 btu penguins.
You state you have a “furnace” be aware thats not controlled the same way as Aquahot!
if you have Aquahot there are 3 zones for heat.
Each zone of heat is controlled by a controller board. 1 board is mounted in each Air conditioner but the 3rd controller is mounted somewhere hidden in the coach. It was quite a hunt to find ours in a false wall in an upper cabinet adjacent to the refrigerator.
When buying new units they provide “New style controllers” for the CCC2 version thermostats.
to use the original thermostats you need to retrofit the “Old style controllers” for the 5 button thermostat. If you do this you don't have to search for the 3rd controller.
Not knowing this we bought the new CCC2 thermostat's. Thus 1 zone of Aquahot did not function until we located and upgraded to a New style controller.
5 extra hours labor to locate and replace the 3rd controller.
This is the first I've heard about the 3rd controller board. I'm planning to order 2 Penguin IIs and 2 new thermostats to do a direct replacement of my 2 Duotherms with 5 button thermostats. Does this mean I need to order another new style board to replace the hidden one? Is this found in any instructions, or learned the hard way?
