There seems to be something about the age range 24-30 where a lot of men suffer a kind of existential crisis. I was definitely the same.
For what it's worth, I'm about to turn 34, and have lived away from home (and in foreign countries) since I was 19. Last Christmas my dad suffered a major stroke leaving him severely impaired - it's a miracle he survived. I decided to move back home (from 6,000 miles away) to help my mother with his care and therapy. I'm convinced that the last 10 months would have broken them both had they been alone. It wasn't a hard decision to make to be honest, as I care about my family, but it did mean completely upending my life and starting at zero again.
I feel a lot of "world angst" - 'no women will be interested', 'I have no social life', 'what must people think' etc. But from a spiritual perspective I can see that it's been a blessing. My previously combative relationship with my father has melted away, he's opened up and become much softer and appreciative, and a family once pre-occupied with the mundanity and low-level anxiety of modern life has been brought closer together.
Having said all that, my situation is different to the OP. In your shoes at 24, I think it's good you have a desire to "do something more", and that's an energy you can draw on. I think you have to ask yourself what will strengthen your soul/spirit, and that could be staying at home or taking flight, depending on your situation. A lot of guys never leave home because they're afraid, and equally I know people who travel the lengths of the Earth endlessly, 100% fuelled by fear.
It seems from your post that your main objective in life is to have a wife and kids. Nothing wrong with wanting a family, but it doesn't come with any guarantees. What's more, you'll probably reek of desperation to any woman within half a mile - in your own words, you won't be able to "start life" until that's all locked down. It seems you don't have an obvious 'interest' or 'passion' (I hate that word), which is fine and normal, but you should be focussed on building yourself as a competent man with a broad skillset. The campervan idea sounds like a cool one to me, especially for someone your age. Travel around, create some stories for yourself, go and do an apprenticeship in something for a year - it sounds like you have a decent amount saved up as a cushion if it doesn't all work out. You're not in a bad position mate. You could be back at home when you're my age
