I'm 74 have an artificial heart valve and pacemaker and I share your concerns about illness on the road but I'm really pretty fit and active. Before I got the heart valve my cardiologist really didn't like our remote locations. I guess my biggest worry is getting real ill or dying on the road and leaving my wife to cope. However, I don't like the alternative; that is, selling the motor home and just staying home. Old age will force that eventually but worry will not. Really, medical help is never too far away with a cell phone so we're not staying home at this point.
