Joys of camping!

What a miraculous piece of adaptive engineering the Airstream has become. This year's 2015 model has for the first time built in ductwork between the inner and outer shell allowing for a sophisticated distributed climate control system. A special design six mode thermostat allows for electric heat pump heating and air conditioning cooling modes, an automatic mode, propane fueled furnace heating when no electricity is available and fan only air circulation. Hot water is either heated by electric or by propane and for the "I need a hot shower now" mode fast response you can select both! Likewise fridge/freezer runs on electric or propane and switches between the two automatically. I have had the breaker pop when we had microwave,  computers and iPads on charge, fridge/freezer, toaster and espresso machine all going at once.... oh the joys of camping! - but we have come quite a long way since that ex-army tent with groundsheet in the 60's!
