"You just made my point and my day.
That's why I wish my E450 had both twin fuel pumps and twin alternators. If what you experienced had happened to you in, say ... Plush, OR or Dubinky Wells, UT ... you would be glad that you had an installed and operating backup pump or backup alternator in your rig so as to get you somewhere closer resembling civilization."
The fuel pump and alternator aren't the only things that may fail without warning leaving you stranded. What about the PCM or BCM? Or braking components such as the master cylinder? If any of these fail you could be stranded as well. Are you going to duplicate everything that, if it fails, would leave you stranded? I don't think you could.
