I did van life with an ex over 20 years ago when we were young and fun and had energy and were trying to save.
It was shit. More than shit really. The summer was mostly fun, but still wet.
Autumn was hideous and winter nearly killed us. And we were lucky enough to be able to park in a friends barn so we weren't wide open to the elements.
Yes, we had absolutely no clue and there wasnt the info available that there is now.
But trying to keep professional jobs (plus study) and just being insanely cold all the time. Never really feeling like you'd eaten a proper dinner or had a proper wash was grim.
The upsides were we were 100% available with accommodation for every party going...which is think was the only thing that kept us going for the 11 months we did it.
I would love a camper van now for holidays, and I wouldn't mind a few nights wild camping. But ill never sleep in my sleeping bag, clothes, coat, hat, towels, rug and under a hairy man purely for warmth again.
And I definitely wouldn't do it as a single woman sadly. Even 20 odd years ago there were weirdos in that community leaching onto women they felt were easy targets
