Renting a campervan in Germany can come with hidden costs. According to ADAC, weekly rental starts at 445 euros, but on top of that, there is a deposit of 500 to 3000 euros, insurance with a deductible, and parking fees of 20 to 50 euros per night.
The price also depends on the season, vehicle class, and the need for a special driving license for models over 3.5 tons. One source specifies that the minimum rental for 6 nights also starts at 445 euros, which may indicate a difference in calculations.
