Porpoising 2019 Cougar Half ton 29 RKS

[modom167]

I have struggled with this for 7 years and no success. Sorry for the length of this post. Here is what I have: 2012 Ford F 250 Super Duty, 6.7 diesel, 4x 4, regular bed 20" tires and wheels, all stock, Goodyear air bags i use for leveling, 16,000 lb. Curt hitch. Bare truck weighs 9,000 lbs.
2019 Cougar Half Ton 29 RKS, 9,500 lbs. , I have installed the Lippert RotoFlex Trail air pin box to help with chucking.

I have tried bag pressure, full water tank, loading heavy to rest and front, replaced Rancho shocks on truck, changed driving styles, literally everything I can think of top stop proposing and nothing has worked

I'm posting this looking for suggestion. Thanks in advance.

Have you weighed your rig loaded and hooked up to determine where the weight is located? It sounds like a weight and balance issue. Much as when flying you need to situate the weight correctly to balance the load nad performance.

Thanks. No I have not weighed rig complete. I don't carry much gear so not much weight to move. I just thought of something. A little unorthodox. I could fill front Gray tank to add hitch weight.
