The space of a van, the kit of a motorhome

Most camper vans have to choose: either they feel open inside, or they have a bathroom. Žluťák has both. The bathtub hides inside the sofa and the toilet looks like a stool, so during the day you get a bright, open space, and in the evening everything you need.

Bright interior of Žluťák with the U-shaped lounge and kitchenBy day: open, bright space
  1. A bathtub in the sofa

    Lift the seat, pull the curtain and shower in a 25 cm deep tub. Hot water from the boiler, plus a second shower outside.

  2. No gas

    Cooking is on induction, water is heated by electricity and by the heater. No gas bottles, no gas inspections, no hunting for refills abroad.

  3. Power for days off-grid

    560 Ah lithium battery, a full Victron system, 455 Wp of solar and charging from the alternator. Induction hob, fridge and laptops all run without a campsite.

  4. Smart van

    Control the lights, water pump and inverter from your iPhone or by voice through a HomePod mini. Plus a camera with alarm, GPS and LTE internet with a roof antenna. "Hey Siri, turn on the water."

Power you don't have to ration

We built Žluťák for travelling away from campsites, and the electrics reflect that. The whole system is built on Victron Energy components, designed and installed by PS Custom.

    Recordings and motion alerts right in the Home app; arm the alarm with one tap.

    The van's location shows in Victron VRM together with battery and solar status.

How Žluťák came to be

We turned an empty yellow van into Žluťák between autumn 2021 and 2023, with finishing touches until early 2025. We did most of the work ourselves and brought in professionals wherever safety and experience matter.

Frequently asked questions

Why are you selling Žluťák?

Our kids have grown up and we no longer have time for the longer trips away from campsites that we built Žluťák for. It deserves someone who will take it on the road.

Can I drive it on a standard car licence?

Yes. The maximum permitted weight is 3.5 t, so a category B licence is enough. The actual weight is lower, leaving room for luggage and water.

How many people does it fit?

It seats 4, each with a seat belt. It sleeps 2 adults and 2 children, or 3 adults and a child, comfortably.

Can I use it in winter?

Yes. It's insulated and has an Eberspächer diesel heater. The fresh water is inside the van under the bed, and the waste tank under the van is heated.

How long can it go without a campsite?

In summer, with the solar, power is practically unlimited. Water is the real limit: you have 90 l of fresh water.

What's the fuel consumption?

10–12 l of diesel per 100 km, depending on how you drive.

Where can I see it?

In České Budějovice, Czech Republic, about 2 hours from Prague and 1.5 hours from Linz. We're happy to arrange a viewing and a test drive.

Is there gas on board?

No. Cooking is on induction, water is heated by electricity and the heater, and the heater runs on diesel from the van's tank.
