Ride with 5er bucking!

So now I am wondering if I take the rear tires from 80 to 70 psi would help, without danger of the tires having issues? This is the part that is confusing to me. I have stock size LT tires load E. So when I rotate the tires from the rear to the front they go down from 80 psi to 55 psi.
Is not the diesel motor Allison trans and the 4x transfer case weight more than hitch weight of 1530? So I went from 80 to 74 actually on the ones mounted on the rear. The truck rides like a tank. The Hitch on the Andersen is over the rear axle and the GAWR is 6084.. Any info would help.......

It would help to know the year and type of tow vehicle etc.

How old are your tow vehicle shocks? Hopefully they aren’t the stock factory ones.

Going down in air pressure isn’t the answer and will generate more heat in your tires.

Bucking is the up and down jerky feeling, right?

That’s exactly what I felt with my truck, the Andersen, and my trailer with a a fixed pin and very low pin weight percentage.

Your first step should be to weigh the truck and camper at a truck stop. Find out the camper’s overall weight, find out the pin weight, and figure out what the pin weight percentage is. My guess is it’s low. Making the front of the fifth wheel heavier may help.

I couldn’t move enough to make a difference, unfortunately. Already had a generator up front and the rest of the storage compartment was small and filled. My toy hauler garage setup is just heavy.

I did NOT experience the same bucking sensation with the B&W Companion before I swapped it out for the Andersen. The garage might not have been quite as heavy so I can’t give all the credit to the hitch.

My solution WAS another hitch, a Trailer Saver TS3. Unfortunately the hitch is stupidly heavy at almost 300 lbs. The exact opposite of the Andersen. And it’s comically expensive at about $3,000. But, we fulltime and I couldn’t have my wife being hurt with towing which is what the bucking was causing to occur.

The hitch weight is 15.4% when loaded and 17% unloaded tires at 80 seems a lot when everything is over the front axle and they are at 55psi. Plus I donít have the money for another hitch and I doubt that the dealer will just swap the Andersen out. I will tell them it is not right and they need to get it right. But not sure if they will care much

I believe your described bucking is actually chucking or the trailer is pushing and pulling your tow vehicle rapidly caused by road joints and hoop de dos. Most people adjust loads, redo their tires and suspension without much relief. They then invest in a rubber or air bladder pin box which solves the problem.

But everyone says the Andersen stops all of the chucking. It sounds to me he has it installed backwards with the ball actually behind the real Axel

Can you get your pin weight any higher? Where are your tanks? Can you put water in them?

And the dealer won’t swap it out, but you can always sell it and buy a new hitch. That’s what I did. Sold the Andersen and put the money to something better.

Chucking and bucking are two completely different things.

Chucking is the 'slop' in the king pin to hitch plate fitment and any play in the hitch/rails. Most noticeable on take-off and stopping but can also be felt at times on rough roads.

Bucking is the up/down (porpoising) forward/back motion of the TV-R/V combination.
