fourthclassC, I think that rescuing her with the RV is a great plan. Yes, it does put you at more risk than just hunkering down in your living room, but it probably involves less risk to her than putting her onto a flight. At least with the RV, you are in control of cleanliness, unlike public transportation.
Do you have more than one person who can drive the rig, so that you can keep rolling as much as possible? Since you won't be stopping at RV parks, do you have a way to empty your tanks at home?
Also (and you probably already know this), bring a lot of plastic bags (like the market uses for produce) and wear them on your hands as disposable gloves when you get gas. I also use rubber bands around my wrists so that the bags don't flop around.
Good luck, and let us know how it went!!
