Cheap campervan for a few weeks of summer remote work (15k€ budget) advice/recommendations

Hi everyone,

I’m thinking about getting a cheap mini camper setup for a few weeks of summer remotework Budget is around 15k€ I don’t have a workshop and I can’t do big DIY builds.

Goal: keep it very simple, reliable enough for a few weeks, and not end up in endless repairs.

Current idea:

• Buy a 10-15-year-old van e.g. VW T5 / Opel Vivaro / Renault Trafic
• Add a camping box or similar for a basic bed
• Use a portable power station (for laptop/phone, PC, monitor, cooling box, maybe starlink.. )
• Mostly stay on campsites and run a long hook-up cable through the window for 230V

Questions:

• Is the simple setup approach reasonable, or are there any practical issues I’m missing? Recommendations? Any tips? For summer remote work, what upgrades are must have? (Ventilation? shades? proper hook-up inlet? internet backup?)
• Any buying tips for 15-year-old vans in this category? I want to use it as a daily car - even in offseason.
• Alternative: Should I rather take a small loan and buy a ready camper for 25–35k€?

Thanks for any experience / recommendations!
