You must make sure your fuel tank and LPG bottle are full before you return your camper. The fuel gauge must register as full and you must leave a receipt for the LPG bottle in the front seat showing that it has been filled within the last 24 hours. Additional charges will apply if this hasn’t been done. If you have prepaid your fuel [PPF] and LPG [PGO], or purchased the Express return pack, then don’t worry - just bring everything back empty!
