I wish I could offer help beyond what I will post here but that was one of my needless (As it turns out) Concerns as well.. What would happen if I died on the road... My wife was not trainable when it comes to most of the RV systems (I tried) However she ended up dying first.
The best advice I can give is make sure both partners are able to do all that needs to be done. Dump/fill tanks. Hook up/unhook. Attach detach and drive.
IF that is not possible.. There are some services.
MASA (Medical Air Services or some such (not sure what the 2nd a is without lookingm Assoication perhaps) is the gold card I have. They will pack up and get the RV home (provide driver, Fuel, oil change if needed) also transport the mortal remains or the living disabled to funeral parlor/hospital (Whichever is more appropriate) near home.
I understand that FMCA which now accepts Trailer owners as well, offers a competing service but I know not details.
MASA, If you are alive but in need of an ambulance, also provides help getting TO the hospital if needed. be it air or ground transport they make sure you don't get dinged with a co-pay/overage
