I have MASA (medical Air Services Assn) which has many features, Including getting the RV home (And feeding the fur kids if I leave food). They also, pay whatever Blue Cross does not of the initial ambulance trip, pay to fly me to a better hospital if needed, or home to a recovery place or to a funeral parlor as needed. What is better unlike so many programs like this (I do not know about the FMCAs) to get that pay the rest of the initial ambulance bill feature I do not need to call from the scene, I can call them from the hospital later.
When My wife died they paid for transport of remains which was very handy.
