The Vrele Gume team traveled 11,237 km by motorhome through 15 countries, from Serbia to the Sahara and Scandinavia, and calculated the costs. Renting a motorhome costs €100–160 per day, campsites range from €15 in Morocco to over €100 in Croatia, and diesel and tolls can add up to €300 per day for two people. The authors note that Germany has a well-developed Stellplatz network, while Serbia lacks motorhome infrastructure.
