Both hubby and I can drive the motorhome, understand the basic systems and maintenance, and ironically in a crisis the wife (me) likely knows more what to do in a crisis than him (LOL). Namely deep breath, don't panic and just get on with it.
We all tend to deal with whatever life throws at us and after every storm comes a rainbow eventually. Hubby will likely phone the daughter and follow her directions, albeit we've discussed and the ultimate goal would be to get back to family and take it from there.
Think it's imperative that we all live in the here and now as long as we can and worry less about the tomorrows that may never come. We know for sure that either one can handle driving the RV back to home base/family as well the deceased for the last journey together as much as legally possible too. Been together since I was 18, so perish the thought of our parting ever, albeit inevitable in reality..
Spent way too many years, planning and dreaming of going FT RVing together, and after seeing mum pass at 55 years, dad at 65 years and father in law at 68, we've both done all the forward planning we want to do for our lifetimes. We now intend to concentrate on living in the moment as long as we can heading into retirement, and whilst being sensible on budget and expenses, we don't intend to compromise when it comes to creating more memories to last us both the rest of our lives either.
For the exact reason you've started the OP, is the reason that both partners should be able to drive and understand and operate the MH. Just getting on with it and embracing it (I hate driving the RV with a passion but do so for the enjoyment it brings overall, and to know I can if need be) with practice, makes the worry of driving it to it's final location a non-starter.
In all reality if anything were to happen to DH, chances are very likely the RV would be sold or handed to family to enjoy.
Guess the bottom line is fear will either drive us forward or hold us back depending on what is the bigger fear. In this instance, "the fear of driving an RV" or the "fear of feeling stranded in the future". If the fears are equally weighted, or there's no alternative options available ie; insurance, family member to fly and drive back, then why would one RV in the first place to just live in fear of a future day that may or may not even materialize?
