Since this is all vector math, it "will" make a difference. The difference is going to be a constant ratio for any given trailer depending on the angles ( it's a see-saw sort of thing). So the difference with 500# in the trailer was 50#, if you had had 1000#, we might expect to see a 100# difference ( I'm making very very grand assumptions here with no math behind it).
As was noted, moving the load even 1 foot fore or aft inside the trailer will make a more significant difference ( that see-saw thing again) and then you have the even more important situation - the dynamic situation - the shifting load - you jam on the brakes the load moves forward taking weight ( aka "normal force") off the front tires of the tow vehicle and off the rear wheels of the trailer in a double + axle trailer and transferring it all to the hitch as well as giving the tow vehicle a kick in the pants when it stops against the front wall of the trailer ( we hope). all of this suddenly changes you ability to control the entire rig at a critical moment
Moral - Secure your load.
Always wondered about that. Don’t have to wonder anymore 🤛😂. Thanks!
Great follow up video!! Thanks for putting in the work.
How about checking the amount of weight on each of the trailer axles while changing the tongue height the same as you did in this video.
Exactly !!
I'm very glad you did this video, and videos Like this too. It's a Learning experience to me still, and I love to learn. Anything. This helps for sure, especially because almost everything is changing and at a fast pace. Good job. Thanks.
Need a tape measure to measure frame to ground at both front and rear. Then note tongue/pin weight amounts.
Thank you thank you thank you!!! Was struggling with decision to fix 1" leveling but was going to cost a bit and lots of work. Glad I don't have to deal with it!
I can add that my findings were exactly the same. I have a 6200# trailer and my truck hitch height was 2.375" higher (at it's lowest shank setting) relative to the tongue of the trailer. I then leveled my trailer and it weighed 950# on my new Fastway scale. I then measured it with the 2.375" upper pitch and it still weighted 950#. I lowered it 4" from level (nose dive) and it stilled weighted 950#. I did purchase a 4" drop shank for my WDH and was able to get the trailer within .250" of perfectly level with my loaded truck. Thanks for your great videos!
This is what UA-cam is for. I really never thought about it. Excellent information
You are absolutely correct, Just like you stated " the position of the weight matters more than the pitch of the trailer".
On a recent trip towing ~7k dual axle cargo trailer with weight dist hitch we found that the angle had a lot to do with tire temps/pressure. Even though things looked level we made a tweak to the chains and had a slight angle, but tires were then dead even.
Try and place heavier stuff on trailer axels. It’s helps in my 30ft TT even if it’s a pain to put it there .
2 videos in one day!
Have you done a test to see how much tongue weight changes using weight distribution bars?
Excellent vid! Gotta love proven results.
Putting this conversation in the context of angle I think causes confusion because people think in those terms w/r/t weight distribution hitches changing the angle of the trailer. If the discussion was weight distribution via a weight distribution hitch on the tow rig then the weight "distributed" via torsion bars into the hitch and frame is taking some weight off the ball but is the same weight total (possibly more due to torsion) on the hitch assembly. In fact you can transfer too much off the center point (ball) and have a light ball and horrific handling. It's a fairly complex topic in totality. I ran into that problem when a certain 'world' dealership put a weight distribution rig on my truck and had nearly all the weight off the ball - the tongue was floating above the ball. That trailer was all over the place scary as heck.
As detail oriented as this dude is, I’m shocked how he leaves his chains just laying in the gravel.
Video is cool. Good info to ease a man’s mind.
I don't. They lock into the Coupler lock when I leave
It is a tandem axle trailer presuming using an equalizer arm between the two axles. When the nose is up the weight of the trailer progressively tends towards being spread over the rear tires and the front hitch. When the nose is down, weight tend to be carried by the front tires and the hitch. Since in the up tilt the distance between the rear tires and the hitch is greater, less weight is carried by the tongue jack than when the weight is more concentrated on the front tires nose down mode. Just think about the extreme cases of lifting or lowering the tongue such that only one set of tires is on the ground. You can also test this by driving the rear tires onto a ramp and letting front axles hang freely down, then repeat for the front wheels on blocks and rear axle hanging down.
Great demomstration. Trailer levelness factors in especially when you are running weight distribution hitches. Being level to slightly nose down allows you to maximize weight transfer. When the trailer is nose up it becomes difficult to get meaningful tension on the bars.
Great video. I’ve always wondered so it’s good to know. There’s not a big difference in the hitch weight but I wonder how much different is the axle load.
Perhaps more important about the tow angle is the impact on sway. Similar to loading the trailer, the geometry can be pro sway or antisway.
I cannot remember though which is worse nose up or nose down - I always go for nose level, and have gone to great lengths in the past to get there.... level is best.
JD, do you know which angle is more likely to induce sway for any given load condition ( especially for a rear biased load...that's just bad )
Agree with others that seeing the impact of the load on both axles with different nose down angles would be interesting.
Good test. Thanks for doing this.
REMEMBER your axle configuration is almost 3ft which will change things dramatically as opposed to putting it directly under the Hitch.. like a 2x4 will break if too much force is exerted at the middle
Thanks for doing this! Great video, good to know.
You have some cool toys!! Great video sir 👍🏻
Thank you for doing this. I was one of the commenters on the other video because the trailers you weighed looked VERY tongue low, that may have been distorted by camera angle, but your 2” estimation seems off. I really want one of those tongue scales. I’d use it once, but I still want one ;).
Can you do a video on balancing the load in a 5th wheel and or travel trailer toy hauler with a side by side or four wheelers in the back? Love the channel!
Interesting!
Unless your trailer is halfway full of water, it really does not matter how high/low the angle is.
Having the trailer not level inpacts wheel and axel loading as well. You want it level so both axels carry equal weight.
I m with Dave Mamilleri, about checking the axle weights and what differences moving a couple hundred pounds of cargo forward or rearward a foot or two will make on both tongue and axle weights. I know it doesn’t matter a lot when towing with a dually and not much even with a 3/4 ton but I watch people with 1/2 tons just about get tapes out to get the loads right
I bet the difference would be more dramatic on a light single axle trailer
Great info.
It help out a lot thanks
Good information to have! Especially when you're riding the weight limits. Sorry but I have to ask an off topic question. Will the Reese goosebox fit inside the opening of a flatbed? I'm getting a flatbed installed in 2 weeks and would like to use the existing ball for my fifth wheel.
Now do one with a half filled water tanker! Not only will you see a difference on the scale, but also get a visual representation of the transfer. I have a single axles 60 gallon tank I pull behind my tractor that I use to spray my fields, and I had first used an attachment in my quick hitch for the 3 point, but my 3 point doesn't have a lock down. I started level, then moved a bit too fast, and the nose when all the way up! Weight transfer in Motion! Water seeks it's own level, which makes for a striking visual on what you were demonstrating here.
A water tank has nothing to do with a static load. It has nothing to do with this conversation.
How much difference do you believe there is when you pull the trailer and the wind is involved with the angel of the nose of the trailer? How much more or less weight would be added or taken away when you either lower the nose or raise it? That may not make sense.
Can you please do a review on the MONTANA 2021 3855BR please
We love your videos. Thank you
What is the load differences on the tires? How would load distribution with 10%-15% tongue weight help with a slight up angle on leveling the load on the tires? My biggest concern when towing is sway and blowouts.
Free body diagram would be the easiest explanation. Some probably still don’t get it even shown the experiment.
I think the fifth wheel weights were off because of the X chocks
Interesting... Does the cargo trailer have torsion axles or a walking leaf spring setup like most RVs or heavier duty trailers?
It's 3 inches..
Off subject but what tires do you recommend for a Cougar RES25 5th wheel with a F250 gas truck. I hear a lot about Goodyear Endurance.
How do I get rid of a slight “floating” of my truck front end while towing? Should I get a 2” raise on my hitch receiver? What would you suggest?
Wdh
Good to know
What’s the GVWR of the trailer? If it’s more than 5k lbs aren’t you supposed to run a W/D Hitch?
Does this also apply to fifth wheel and gooseneck trailers?
What hitch lock do you keep on your bumper pulls?
If you have ever used a wheelbarrow you already knew this.
You will get more weight shift just by going up and down hills.
The difference was your man door swinging front and back. 1:57 🤣
I think you should just chock one wheel on each side with wheel chocks
Why not throw a level on the A frame, so we can tell when it was level, rather than just eyeballing it?
I think the point is that with several inches difference, it barely made a difference.
Yes, perhaps.....but it would have taken minimal effort to do a proper test, rather than estimating.......
Before the video even starts in going to call bs. The trailer is using the axles a nothing more than a fulcrum. The weight is still pushing down by gravity whether it's 1 inch or 10 feet off the ground. The flat floor of the trailer is bearing the weight and setting it on the tongue or axles not withstanding the angle. Maybe I'm wrong, but I'll watch and find out. Ok 1% per inch. Is it enough of a difference to make a difference? I don't think so.
Because it is a dual wheel trailer. If it was a single wheel it wouldn’t be that different
BUT WAIT...what if it is a SINGLE axle trailer?
This. I'd think the weight difference in the video was due to it being tandem axle...
Where did the toy hauler video go???
Into the abyss.... It will be back soon
Hey JD, I went to watch your video on the toy hauler from earlier today and now it’s gone...... are you going to reupload it?
Yes
Yeh 🤣 after he edits himself out of it.
JD if you decided to shave and weren’t wearing a baseball cap do you think anyone would recognize you if they walked passed you? More likely not 🤣, nothing to worry about.
Are these spring and equalizer or torsion axles?
Leaf spring with equalizer
Weight sharing on the suspension/tires might be more dramatic.
I was pretty shocked that trailer has 900lbs tounge weight..
Did this one get edited???
Nope. Raw
Best thing to do really is go to calibrated public scale and find out the exact axle weight for each individual's RV.
Yeah and squat on truck a little, and when you accelerate some ..
Amazing. People lie. But mathematics/trigonometry doesn’t. Hmmmmm.
First
You all just failed High School level physics!!! The weight will be the same in the range of normal towing angles. Yes, there will be a slight change in weights at the tongue depending on angle, but not perceptible at the few degrees of angle for a towing setup. Duh!
That was kind of the point of this video.
Your point is not proven. You're testing a static load. All of that changes when you're moving down the road on a live suspension. You're not factoring in the inertia generated during bouncing which drives the tongue weight below or above the hitch and the resistance needed to overcome that.
Agreed. This was not a comprehensive test while towing. The point of this video, as I said in the beginning, was to revisit the topic of checking tongue weight when static. This was due to folks requesting more information about a video I had previously done.
