That is going to be one big project. I don't know if you have been over to @alexbeyman ' s, he is doing an electric car camper. He has found some very useful things for his steemmobile. One is an on demand propane/electric portable hot water heater. Plus he has a lot of other gadget finds that he has found. If you haven't seen his post they are worth it, plus like you he is a good writer.
