Sounds very like the Experience of Mrs B and myself, as outlined above. You van even has similar layout to the Autrotrail we owned as van No3 😊.
I would add, that on such lengthy travels (time wise) as you describe, we found, it is not like being "on holiday", we lived pretty much as if at home, eat out sometimes, eat in sometimes, some. days, laze about, some days "do something", there was never a time when we felt we "had to do something", we just did what we wanted, when we wanted.
But, as you say, it is not for everyone.
The bit of our story I did not tell, I spent a considerable time working in Gibraltar. Most weekends, I used to take myself off to Tarifa area, to escape the place. There used to be lots of people in Campervans/Motorhomes (all nationalities) and it struck me as a good wheeze. `When We retired, a few years later, we went on a "package" holiday, just to "celebrate", it was horrible (in my view), airport procedures, airplane full of obnoxious people and their offspring, hotel, similar. I decided, "never again", and, a few months later, we bought a motorhome.
