I'm looking for a 4-person wagon stroller that combines functionality and comfort. It should be suitable for outdoor activities, easy to maneuver, and have enough storage space for essentials. Safety features like seatbelts and sturdy construction are a must. Additionally, I'd appreciate any details regarding customization options, available colors, and bulk pricing. If you have any recent models or additional accessories that enhance the user experience, please share that info too. Looking forward to your response!
