Air bags/Blue Ox Hitch - Okay?

a set of good rear shocks should solve that "porpoising" problem you have.

That's really good information. I have absolutely no sway at all, just those two or three big oscillations every time I encounter a good bump or dip.

The shocks should be OK for awhile. I notice that my F250 rides better with some weight in the bed.

There are some roads out there, especially Interstates, where truck traffic creates a dip and peak situation. It can cause a lot of bounce and oscillation when towing.

A better idea may be Timbrens or Firestone Work Rites. They only engage when you need them. Their progressive designs make them self adjusting so there's no fooling with them for different loads. I have Work Rites and use them with my Blue OX with the 1,500 lbs bars. I haven't noticed any reduction in performance. I chose the Work Rites because lots of people report that their Timbrens get very stiff in the cold. The Work Rites are made from a different material that stays flexible even in the negative temps.

Also you could look into new shocks. Sometimes OEM shocks are not the greatest. I switched a basically new pair of OEM shocks for Bilsteins and the difference was night and day. The Bilsteins did a much better job of quickly catching the oscillation and stopping them.

Airbags won't reduce the bounce you are experiencing. In fact, they can make it worse because they have less resistance to rebound that leaf springs.

You really need better shocks. Good Monotube ones. I run KYBs. Bilsteins are good too. Make a world of difference for heavy TTs.

I have the same setup (Blue Ox 1500). My TT tongue weight is about 1300 lbs which represents, I believe about 14 percent of my total weight (9200 lbs loaded).

If your TT runs just under 10K loaded, and your tongue weight is only 1075, You're at 10 percent or less. You should be closer to 13-14 percent. I don't know if 10 percent TW contributes to the bounce you are getting or not. I will say when I get on uneven concrete roads that create the porpoise effect, it takes about two 'porpoises' to settle down. That's not bounce, and happens infrequently.

Try increasing tongue weight.. maybe that will help.

I'd look at new shocks before air bags, if you are bouncing like you posted.

What shock absorbers do you have on the truck? Do you carry any weight in the truck bed?
