I was wondering if I have a 24 foot floor on my trailer (4800lbs emply)

truck : 2008 2500hd duramax with air bags

I have a 16 foot generator weighting 8500 lbs

I have 2x 7000 lbs axles on my trailer

where should I be loading the piece so that the weight is evenly distributed ?

todya I carried that piece and the trailer always was jerking front to back

it was very annoying !

I was 75 lbs below truck gvwr at 9125 pounds

any help would be very appreciated !

What kind of trailer, bumper or gooseneck? If its a gooseneck, what brand of gooseneck ball do you have installed?

Biggest thing about torkflex trailers is making sure the deck of the trailer is as close to level as possible. With a 24' deck you should be able to get within a couple inches front to back of level. When it's nose high or low, one axle is carrying most of the weight.

Generally speaking, if you center the load on the deck of the trailer you will be good. Goosenecks are much more forgiving than a bumper pull is when it comes to hitch weight.

I would set the generator 4' back from the front of the trailer if I was loading it.

Btw, if you have a B&W hitch, go check out the B&W thread in the LML forum. You might be another unlucky one. My hitch did the same thing.

yeah its a reese gooseneck hitch

the thing is is never stops moving front to back when hitting road bumps on highway

from the center of the axles, the center of the generator was 8-9 inches in front and it was nearly in center of the trailer itself

but it was pretty heavy

but I was 100 pounds lower than my truck gvwr

If the trailer was level or close to it, check to make sure the mounting bolts on the truck hitch are tight. Get a rubber hammer and give the ball itself a really hard smack to see if it might be loose. Make sure the clip that holds the ball in the hitch is installed.

On the trailer make sure the bolts holding the coupler are tight. Check to see if there are any cracks where the coupler welds to the frame. And finally check the coupled itself to make sure there is very little play when the ball is inserted and latched. You can insert any 2 5/16" ball in the coupler. When pushing up on the ball there should be no excess play front to back or side to side.

If you were considerably nose high one axle would have been overloaded and could have caused the shaking when hitting bumps.

can it be possible that on the hole for the hitch ball can be gapped too much ? (on the trailer)

the trailer has 10 years of service

can my "play" maybe comes from there ?

because im all within limits of each unit (truck and trailer )

when I was towing loaded, the trailer was nearly leveled, maybe nose down an inch or less

Absolutely couplers can wear out, especially if not greased. Like I said grab a ball and feel how much slop is in it. You can buy just the lower section of the coupler they're pretty much universal. I would check everything over as well just to be sure.

ok ty

Jerking front to back IMO would indicate a problem with the trailer or hitch. Sway would indicate a problem with load position.

maybe the trailer suepension or what can it possible cause that to jerk front to back ?

my hitch head is brand new

but the other parts are quite old (10 years)

but what should I look around for ?

is it mendatory that unloaded, the trailer to be leveled

mine now its raised in the front by 1.5 inch in the front

and the ride is harsh when driving on uneven highway but when driving on new freeway its prefect but it tend to sway a bit now...

I guess Ill have to readjust it but leveled ?

If the trailer is pitching into the truck on rough road, I'd suggest to move the load forward on the trailer. You have air bags and can level the truck if the rear sags a bit. I usually run at about 5800 lbs on the truck rear axle, 3900 on the front, a bit over on the truck but rides better. Better than the rear of the trailer wagging the truck, sideways or up/down..
