Trailair was first to the market with air ride technology for fifth-wheel RVs and still leads the way with innovative fifth-wheel pin box technology. Our new Flex Air Pin Box combines our time-tested Trailair air ride technology with our Rota-Flex pivoting head to significantly reduce fore to aft movement and vertical tug-of-war between a fifth-wheel RV and tow vehicle.
