I pulled the Suburban propane heater out several months ago and installed an Espar D2, diesel powered heater. I picked up some extra storage space as shown in the photo. The new heater is in the red box on the right side. The red box shows what additional storage space was added. As anyone with a “B” size RV will agree, every inch counts as far as storage room (this added about 1.5 cubic feet of storage space). The hole at the bottom of the picture, in the paneling, is where the old heater output vent went. The black object below it is the new vent which swivels if you need to direct it in a specific direction.
I now (finally, about time, etc.) built a box to cover the heater and divide off the inverter/converter shown on the right side of the above picture. One good thing about the Espar is it can be mounted in a tight area without a lot of worries about clearance. The only worry is when servicing it being able to open it. Since I would have to remove part of the gaucho anyway, this box adds two extra screws I need to pull to get the box off the heater. You can see on the picture the door that was added in the opening for the old heaters vent.
The new space is also accessible through an existing door adjacent to the new door.
