Hey John, since we know your 2025 Grand Design Solitude 27D has a Lippert 1621 style pin box currently the correct Curt air ride cushioned pin box would be the Flex Air part # LC328492 which offers vertical and horizontal cushioning. Because of that it is my favorite cushioned pin box to recommend. What fifth wheel hitch do you have currently?
