I called my contact at Lippert and asked about the weight of the Lippert 1621 pin box, part # LC1191191 versus the Flex Air 18,000 pin box, part # LC328492.

The # LC1191191 weighs 98-lbs. The # LC328492 pin box weighs 232-lbs, so it weighs more than twice as much as the # LC1191191

Great question, Jeff! When the Rota-Flex first came out it renovated what a pin box could do and be, but at this point in time that technology is a little more dated and the Gen-Y Hitch Shock Absorbing 5th Wheel Pin Box #325-GH-8040 is the "new…
