Welcome to the Airforums...you'll find lots of information and knowledge here, so dig in!
Food for thought...are you planning to travel with your Airstream? Or stay put and turn it into a "park model" of sorts? I ask because you say you want to go all electric. If you intend to travel with your trailer you will undoubtedly run into situations where you do not have access to electricity to run all your appliances. Yes, you can do a lot with solar but when you get into AC, water heating, etc (big energy draw items) it may prove more efficient and to use LP. That's why they are equipped with electric and LP systems...that whole traveling thing. Just something to think about as you proceed.
Whatever you end up doing, have a blast and enjoy your journey! And keep us posted on you progress.
