If you have an adjustable ball mount or coupler on the trailer crank it up.
Raising the height of the tongue will go al long way to smoothing out those bumps also. If the trailer is flat and level, the springs force the tire to go straight up to absorb a bump, but if you raise the tongue, the wheel can move up and back (because the angle of attack changed) to absorb the impact. This is often all that is needed.
Best of luck.

"Having a trailer that is not level will cause it to fish all over the road and may cause the driver to lose control."
Care to explain the logic behind that statement.
Sway is caused primarily by a lack of tongue weight, raising the tongue by even one foot would cause (on an standard 18' trailer) about the same weight reduction on the tongue as a seagull having a good dump on the back of it would cause.
Best of luck.

Ah see, there's the problem, the question was "How do I stop my EMPTY trailer from bouncing around so much?".
The devil lives in the details, the right answer to the wrong question is still wrong.....
Best of luck.

Wing, no I don't have a problem with you, but when you make an inflamatorty statement like saying that raising the coupler when towing an empty trailer will cause it to sway uncontrollably, and could cause the driver to lose control, that is plain wrong and needs to be corrected.
Period.
BTW, "What they do in Canada..." is pretty much the same as they do south of the border, the regulations are pretty much standardized all across North America.
"...actually when the tongue weight exceeds 500 pounds a weight-distributing hitch is recomneded." and this would be when you're towing with what? A Honda Civic?
Best of luck.

I saw ZERO back up for your statement about raising the tongue causing a lack of control. Please repost it.
My backup, it's called physics, shall I walk you through the math?
Speaking of ignorance, the reference to a Civic was something called being facetious .......
BTW, re-read the whole thread, my suggestion was NOT to raise the hitch a foot to eliminate sway. In fact the only reference to sway was yours.
The question asked was how to stop an EMPTY trailer from JARRING the tow vehicle quite so much.
Yes, I have an idea what an 18' tandem 5k # axle trailer would weigh empty, probably about 2,700 #, at least that's what my BriMar weighs.
BTW, according to Pythagorus, the change of 1' in the hitch height would maens about a 3.81407° change in the attitude of the trailer, assuming the frame rails are structural C channel and it has a steel deck, that might make about a 1/2 pound difference in tongue weight. Given it's starting at about 450 pounds, that would be maybe a little over a tenth of one percent reduction in hitch weight.
Best of luck.

Ok, I was wrong, you were right, now that you pointed out that this guy wants to put 80,000 pounds behind his F150 on a 4 axle 53' highway trailer I agree, it will definitely have a sway problem......
BTW, it is arrêt, and ouest ..... más claro ahora?
Best of luck.

Dave, you are of course right, it should be 0.384°.
There are several other engineers on this site, perhaps one or more of them would care to verify the math?
It seems I proved my case based on undisputed physics and mathematics. I hardly feel either could be considered BS.
"Your math is very weak..." care to elucidate?
"Now for a slow learning Canadian, I will spell it very slowly for you." please keep cheap shots and personal attacks out of the facts. Children rely on such tactics when they have no other arguement to make. This is an adult forum.
"...when we Job Rate a customer and sell him a truck..." Can I take it from this then that you are a D/C sales rep.? Is your entire trailer knowledge based on a D/C trailering brochure?

I do not find a lack of basic english language skills to be "inflamatorty".
"Now for a slow learning Canadian... " that was "inflamatorty".
"....I will spell it very slowly for you." I would prefer you spell it correctly, but do as you wish.

I thought there was a difference between a typo. and inventing a word, but apparently not.
I'm not a "so called" engineer, I got a goodly edjumakashun at MCB Quantico, I'm a full-on papered Injunear.
So like, take off!

Thank you Wing.
I think there's a typo. in the goat-truck sales paperwork somewhere. I believe the trailer is supposed to be level AFTER loading, not before. With a anything north of 500 pounds way back there on the hitch of any 1/2 ton pick-me-up truck, the bumper will need caster wheels under it, it will be so squatted down it will nearly drag on bumps.
In most cases with a 1/2 ton, using the ball mount that results in a level LOADED trailer, will cause the tongue to sit high enough when unladen to result in a smoother ride.
A little careful experimentation might be in order.
Best of luck.

Wing, I have no desire nor goal of impressing anyone.
"...on fresh laid manure." Interesting analogy considering we're replying to YOUR posts.
As for tow vehicles, all you have to do is click on my pictures, #'s 19 & 20 show the SMALLEST of my tow rigs.
BTW, boats are designed light, it's kind of a requirement for floating, and average 22' runabout weighs about 3,500 pounds, if it was a cuddy it might weigh 5,000 pounds, in either case the majority of weight, the engine and fuel tanks, are at the very rear, which is why the tongue is so relatively long on a boat trailer, in an effort to balance it up.
I repeat my earlier statement, if you need a WDH with a ~500 pound tongue weight you don't have enough truck out front. I used to tow my boat between Toronto and Florida twice a year, and did for years. There's a few hills along that route too, from tip of propeller to tip of hitch was about 45' and it weighed about 10,000 pounds including the tri-axle trailer it sat on. No WDH was ever required.
Best of luck.

Wing, is your first name Ray by chance?
13 year old? Followed by racial slurs, and personal attacks? You're kidding right?
Again, you read what you wanted to see, NOT what I said.
I said "boats" are designed light, but that would be like reading "empty trailer" now wouldn't it? I know very well what a AMTRAC or AV weigh, or even an LCAC for that matter, I had two shiny silver bars on my uniforms collar....... I learned all about that stuff.
BTW, 'Frog' is a term used to refer to the French people by some, at least get your racial slurs right, I'm an Anglophone. While we're at it, please keep your slurs to yourself also, we try to keep this is a family-rated forum.
As for the term "goat-truck" it is becoming a very common slang term for Dodge's trucks, in fact I first heard it in Florida where I used to have a house, and spent my winter's every year. It comes from the animal on the hood ornament, you know, like the Mack bulldog?
Best of luck.

EW, I was trying to use simple plain language, by 'tongue' I meant the distance from the coupler to the centerline of the suspension. If you look at two equal length trailers side-by-side, one for a boat, one for a car, you will see that the suspension is much farther back on the boat trailer, nearly at the back in fact.
Most boat trailers don't have a tongue by the conventional way of thinking. The frame merely converges to a coupler. If you look at most boat trailers from a purely design perspective, they don't have anywhere near as much "tongue" as a regular trailer since the forward tip of the boat is actually really close to the coupler. Some of the larger boat trailers have a telescopic tongue feature that allows you add as much as 10' to a trailer to aid in launching.
Best of luck.
