Good Sams may be able to help you ... I (Some years ago) Bought a membership in MASA (Mediacal Air Services Assn I think) and they will pay a professional driver to drive your rig home if you should be sick, injured or die "on the road".. In fact they paid for the gas for ME to drive it home when my wife died.
They also pay to fly you (or your body or ashes) home on one of their private jets.
Oh, and if you are in an accident, or if you take sick and need to travel by ambulance.. They will pay whatever part of the ambulance bill your regular health insurance fails to cover.
I know of no better policy. Mine was a single payment plan, I think they now sell by the month.
Home was where I park it. but alas the.
