My Outback was a 50 amp TT, wired for a second AC...I moved the main unit forward and put a heat pump in its place. Where we live, we have to keep the heat on to keep the chill knocked out. There were times we were spending $100+ on propane a month. Once the heat pump was installed, we went nearly 7 months without having to fill any propane... I did the work myself, it was well worth it in the end, especially since the thermostat just needed a temp set, it would cycle the AC or the heat to maintain the temp. If the temp split was >5 degrees coller than requested temperature, it would auto cycle to furnace to catch up, then go back to the heat pump.
