I would recommend Bob Wells' "How to Live in a Car, Van or RV". It has the basic, nuts-and-bolts info you need to get out there.
Remember you don't need a sweet craftsman conversion to travel, save money and have adventure. That's just the (expensive) icing on the cake. Starting simply is far better than not starting at all, and lets you add what you really need and nothing you don't.

Im not sure on euro vehicles (maybe the large ford transit with bike carrier?), but there are a few good newbie guides out there. Bob Wells has a pretty good ebook that covers the basics https://www.amazon.com/Live-RV-Debt-Travel-Freedom-ebook/dp/B008S129XY His website cheaprvliving is a good resource too, if you dig through his articles and blogs you can basically glean all the info from the book too.
If you have a vehicle check out Bob Well's CheapRVLiving YouTube channel: https://www.youtube.com/c/CheapRVliving/featured
He explains how to find free camping and all the other details of van/car life.
He also has a book that explains the most important parts and it's only $3.00: https://www.amazon.com/Live-RV-Debt-Travel-Freedom-ebook/dp/B008S129XY/ref=sr_1_1?crid=27MY6S9K03A1R&keywords=bob+wells+cheap+rv+living+book&qid=1653056951&sprefix=bob+wells%2Caps%2C173&sr=8-1
Bob Wells at www.cheaprvliving.com shows how lots of people are doing on $1000/month or even $500/month. Read his book, it's excellent.
