Weight testing oak

I pulled twice weight of tow vehicle today 38 mph was Max speed . Before you feel the death sway .
That's with 2 axel 6000 lb brakes dialed in and 12,000 lb weight distribution hitch. Is that normal or was it a load transfer issue . Yes at 39 mph you feel it start swaying . Any pointers are welcome .

The tail will wag the dog when you have less than 10% or less of the load on the tongue. How much was in the trailer and what did the tongue weigh?

 

I've had the tail wag when I had too much tongue weight too. There was no way I was going to empty the trailer of all my dads possessions to redistribute while on the road with just him.

He would get nervous and drive under 60 where it would wag. Let him drive the first 4 of the 30 back to NH. I found I could just power through and it would straighten out at about 67, so I stuck him in the passenger seat for the rest of the trip. No way was I gonna do 55 from Ft Worth to NH!

 

Careful out there fellas!

 

What do you mean with axle brakes dialed in?

I routinely pull more than double I've trippled the tow vehicle weight.
The only time I've had bad sway was at 75mph pulling a tlb.

Wheelbase and tires can make a difference.
40mph seems really slow for it to happen.

I'd think about the tow vehicles tires, the trailer tires(matching?), trailer type(reputable?) And if the weight distribution hitch is set up correctly.

 

Sounds like you might have been a little light on the tounge.

 

Brakes on trailer is what would stop the sway at 45 mph 38 mph was magic number to stay at. I think I should of tightened the weight distribution hitch even tighter. Was my first issue. Trailer and load was 12,100 lbs tow rig 5600 lbs

I think I'd rather crash than have to listen to that music he had on.

I used to tow the big trucks like he was driving, so I am well versed in the craft

 

It didn't help him that he had a rack on the back of that camper with all that weight on it.

 

Was the weight properly distributed side to side? I towed a lot of weight once with a half ton. Excavator was too far back and off to one side. I pulled over and adjusted and was fine afterwards.

 

Trailer tires may have been soft or underrated for what you were doing. Rear tires on the truck, also. Or not enough tongue weight. Never seen a load get squirrelly with too much tongue weight. Tightening the weight bars would have made it worse

 

I agree with what Huskihl said. To much tongue weight can make your steering feel light.

 

Interesting . Maybe if I would of tighten up weight distribution hitch it transfer more weight to the front . But it's got coil over shocks in back so I think there was more weight on tongue than I thought also.

I'd put money on that load being tail heavy.

 

To the eye that doesnt look like 10% tongue weight....looks like you need some more weight up front. Looks like the back trailer axle is loaded more than the front.

 

I'm thinking these bundles don't weigh the same either. Back ones were probly heavyer . I should of took a straight on picture . I'm going to try 2 bundles next time . Just see how it acts . Put bundles together in middle . This load was my first attempt.

Yep just too much weight behind the tires.
Tahoes and Subs are pretty soft sprung. With that kind of weight on the trailer, I'd load it with 5 -6" of squat, and then use the load leveller to lift it up so it had 2" of squat.

 

Here's a picture of the whole rig . That's oak.

Are you talking squat on back wheel well of Suburban ? Weight distribution hitch set for empty. Then let him load so it's squats 5 to 6in on the wheel well. Then crank the distribution hitch up 2 in on the back wheel well.
Is that what your saying ? I have coil over shocks on suburban also..
