Avoid the Camper Disaster

"You spent months building, lovingly varnishing every board. Then you're at the inspection. The scales say: 3,650 kg. Too heavy. The front axle? Overloaded because the big batteries and water tank were placed wrong. The handling in curves is spongy and dangerous. All for nothing? Not with VanLogic. We built this app so you know what the final result on the scales will look like with your very first click."

Read our blog. What's important for van conversions? What are the dangers? How can you avoid them?

Calculating Sprinter conversion weight: What you need to know before turning the first screw

Reading time: approx. 6 minutes

Most campervan builders make the same mistake: they start building without knowing how heavy their van will eventually be. Months later they're at the inspection — and the scale shows a number they didn't expect. This article shows you how to keep weight under control from the start. Not after the build. Before.
