Trailer Sway

I just towed my 10,000lb trailer in my CC/SB LMM for the first time loaded to the top with broken cement. I noticed going down the freeway around 60-65 mph that the trailer was swaying pretty bad, I had to continously slow down to about 55 mph to stop the swaying. My question is why is it swaying so bad and if there is a solution to this???
The LMM has the built in brake controller and worked fine!!!

It's usually caused by improper loading, having too much weight behind the axles and not enough on the tongue.

Too much weight behind the axles it lifting up on the tounge. I had that problem with a old F 150 if the trailer wasnt loaded right it would take the load off the back wheels of the truck and make it sway.

my $.02

Sway bars are OK but seem to only be correcting a problem with improper tongue weight.

An example of this is my camper. We went to the factory and towed it home without a sway controller and all was well. After we took delivery from the dealer and loaded it up I had a sway issue which was not there before. Only thing we figured out is that it has a lot of rear storage and I put too much weight in the rear. After I rearranged some of the items the sway is gone.

The sway controller helped in the interum but I like it a lot better now without it even wanting to sway.

Hey Mike, still interested in the exhaust!!! I did another tow with the trailer this time I put 56 sheets of 5/8" 4'x12' drywall in the trailer and it did the same thing??? Could it also be the hitch (Rapid Hitch Adjustable) that is responsible!!! The load was even front to back and center on the trailer...

You're not using a weight distribution or sway control hitch? What's the rating on the factory hitch?

what's the tire pressures on truck and trailer, is the trailer level, got some pics of the loaded rig, are the helper springs on the truck loaded, what kind and size of hitch tube (pic)?

all the above will make it sway.
