You can travel with anyone in your motorhome or caravan, as long as they are part of your travel company. According to MyCamper's terms and conditions, the travel company includes the renter and anyone else using the vehicle during the rental period.
However, there are a few important things to keep in mind:
The owner of the vehicle may set a minimum or maximum age requirement for travelers.
Only approved drivers may drive the vehicle. If you want to add extra drivers, they must be registered and approved by MyCamper before driving.
The number of passengers must not exceed the legally allowed limit (i.e., the number of seatbelt-equipped seats in the vehicle).
The renter is responsible for ensuring that all members of the travel company comply with the rental agreement.
If you have any specific questions, such as bringing pets or traveling with children, it's best to check the vehicle listing or ask the owner directly.
