Regarding the free space. I assume you mean the space of the current furnace. In mine I have a space for a catalytic heater and no furnace. In place of the furnace (where yours is located) I have three kitchen drawers. The catalytic heater mounts under the left side of the kitchen counter down low by the door and floor. With the proper heater (look at Wave 6), and the back door window cracked, a roof vent cracked, a functioning CO2 detector, and the oxygen deprivation shut off on the heater, you might find you don't need a wood stove. I've learned the catalytic heater just sips propane and a stove top doesn't take all that much. With an additional tank stowed somewhere you might get several weeks of boon docking. I am replacing my horizontal mount tank (where your is located under the fridge) to a vertical in the stool closet accessed from the back right wall of the camper. With one tank there is still room for a bathroom sink and drain, and without a bath sink you could likely get two 20lb tanks in that corner of the camper, freeing up storage under your fridge. Just need to build a tank cabinet.
