  • The Best Campervan Sinks for RV Kitchens & Water Systems
    Our campervan sink probably gets more use than any other accessory installed in our Sprinter conversion. We use it washing up, preparing meals, making coffee and even as a kettle store when we’re driving.

  • A Complete Guide to Portable Composting Toilets for Van Conversions
    For a couple of years, we had a Thetford cassette toilet in our Unimog camper. The emptying experience was far from pleasant. We hated it. Chemicals are expensive, and finding places to empty them responsibly was often difficult when we were off-grid. Because we live in our van full-time, it was a compromise too far for us.  So when we were …
  • The Best Portable Hammock Stands for Camping in 2021
    Lounging in a hammock is idyllic and the best way to relax on a warm afternoon on camp.  The problem with hammocks is they need a couple of trees relatively close together to hang them on.  You need to secure them high enough so your butt doesn’t drag on the floor but maintains a comfortable …
  • The Best Non Electric Camping Coffee Makers for Campervans, RVs & Camping
    Our love of coffee means a decent coffee maker is on virtually every list of campervan essentials. It’s the first thing we reach for each morning and the perfect beverage after a long hike. And a good cup of coffee around a campfire takes some beating. Whether you’re looking for a gift for a van lifer or packing …
  • Campervan & RV Wifi Guide: How to Get RV Internet in 2021
    For many, campervan and RV wifi has become more of a necessity than a nice-to-have.  If you use your van to seek a few days off-grid, internet access is probably the last thing you want or need. But when living long-term in your van, your needs will probably be different.  You might need to work …

  • RV Generators: The Definitive Buying Guide
    Comfortable off-grid RV living depends on the availability of enough electricity to power your appliances.

And increasing the battery …
  • How to Use a Digital Multimeter | The Champion of the Campervan Electrical Toolkit
    A multimeter is one of the most useful tools in an RV or campervan toolkit. When installing a campervan electrical system, you’ll use the handy tool all the time. You’ll test your solar panel’s output, battery levels, cable continuity, and much more. Even once your van conversion is complete, the multimeter is the first tool to reach …
  • RV Battery Monitors for 12v Electrical Systems
    To avoid running out of electricity when living in a van off-grid means closely managing the leisure battery bank. Using more power than the alternator or solar panels supply will eventually lead to flat batteries, no matter how big the battery bank.  And, over-discharging the battery can shorten its life, leading to costly replacements earlier than necessary. A battery monitoring system …
