Cushioned Pin Box Recommendation for a 2012 Keystone Outback Sydney 330FRL with Lippert 1621

Question:

I have a 2012 Keystone Outback Sydney model 330FRL. It is 36 foot long and loaded weighs about 12K. I pull it with a 2008 Silverado 2500 diesel. I would like to improve the pull of my camper. I currently have just a standard Lippert 1621 pin box and am looking to improve the pull by installing a Trailair pinbox to help with chucking, porpoising, and ride harshness felt in the truck when hitting bumps with the camper. Which model would you suggest for my setup? Thanks in advance.

For your 2012 Keystone Outback Sydney with a Lippert 1621 pin box the Trailair pin box I would recommend would be the Flex Air part # LC328492. The internal air bag and built-in strut work with the rubberized pivoting head to achieve a dramatically smoother ride.

I attached a review video for this pin box for you to check out as well that covers the features of the pin box and how it cushions the ride.
