Have a 29' 5th whl, weight 8500#.

Am considering adding a shock absorbing pin box.

Who has experience with them; which brand and model is recommended?

Cost?

Thanx a bunch

We have a Trail-Aire 21k gvwr pin box. It works great. Unfortunate for us our fulltime rig weight has crept up to ~22.5k and we will have to swap it out for a more HD pin box. We are looking at Trailer saver hitch, which has the shock absorbtion in the truck/hitch.

I have the airborne pinbox with an airbag and shock absorber, about 5000 miles on it so far and am very happy with it.

I tried a trail air hitch, both the TS3 and the TS2, neither helped the bouncing of the truck, in fact the truck bounced worse with the two hitches than with a regular solid 20k Reese hitch, to the point of being uncontrollable. I ended up reducing the spring effect of the truck to get the best ride by removing the snubbers on the front of the overloads, and set the rear tires at 65 lbs air pressure as well as putting the most pin weight on the truck as possible. This is with a 2011 3500 dually with 3000 lbs pin weight and 15,500 trailer weight.

We added the Demco GlideRide extended pinbox to our 5th wheel. It reduced fore/aft "chucking" when braking on rough surfaces, etc. by probably 80% to 90%, but it isn't designed to do anything about vertical motion which is no problem with our rig.

Which pinbox is right for you depends on what problem you're trying to solve.

Have TrailAir tri glide on ours (from manufacturer). Driving the same roads it makes a world of difference. It really reduces the shock on the trailer and truck on our wonderful PA roads. (We just switched trailers this June and the new one is heavier)
