The quick reply is, No.
Typically looking for detailed data on trailer towing is troublesome at finest.
After we purchased our present trailer and tow automobile I knew that we'd be near the utmost capability specs for each. A lot of the self-proclaimed or perceived specialists would say purchase an even bigger tow automobile if you will be near the tow automobile’s most specification for gross trailer weight and/or tongue weight. In different phrases, “purchase an even bigger gun.”
I'm not a hunter and I've by no means hunted. However I do know you don’t hunt elk with a pocket knife (too small) or a rocket propelled grenade (too huge). You employ a rifle with the proper caliber of bullet and different attributes that mixed are a match for taking an elk. And so it's with our tow automobile. The producer (Ford) says we will safely tow a trailer that weighs as much as 9,200 lbs absolutely loaded so long as the tongue weight is between 10% and 15% of the trailer’s weight and the tongue weight doesn’t exceed 920 lbs utilizing a weight distribution hitch also called a WDH, and on the identical time the tow automobile can't exceed the Gross Automobile Weight Ranking, or any Gross Axle Weight Scores, and the Mixed Gross Automobile Weight.
However the query I had was whether or not or not tongue weight included the 100 lb. weight of the Equal-i-zer weight distribution hitch I bought with the trailer, after which later the load of our present ProPride hitch. At first I assumed I knew the reply was no, the hitch weight is just not added to the tongue weight, however in some way I forgot that and began including it. In order different like-minded individuals do, I began doing analysis to clear my cloudy and now confused mind. And I lastly discovered the reply, which I'll share and clarify.
An enormous drawback with Web boards, blogs, web site articles, and all issues Web is far of it's opinion. And because the saying goes, “opinions are like assholes, everybody has one.” Then again, these so-called informational sources usually will lead us to the precise reply, if we search diligently. So I wish to current what I've realized utilizing diligent analysis.
To soundly tow a trailer there are a number of capability specs that should be complied with. It is necessary that not even considered one of these specs is exceeded. In case you keep inside all of the specs decided by each the tow automobile producer and the trailer producer it is possible for you to to soundly tow your trailer. These specs embrace:
- Complete weight of the automobile with the trailer hooked up
- Complete weight of every tow automobile axle with the trailer hooked up
- Adjusting the load distribution spring bars in line with the tow automobile producer’s process
- Complete weight of the trailer when it's disconnected from the tow automobile
- Weight of the trailer’s axle(s)
- Weight of the trailer’s tongue (coupler)
- The whole mixed weight of the tow automobile and trailer, as specified by the tow automobile producer
So let’s begin firstly and use my 2012 Ford Expedition for example. The Proprietor’s Guide, Towing Information, and labels hooked up to the automobile present the wanted data.
From the Towing Information
Our Expedition is the 4X2, has the three.31 axle, and the Heavy Obligation Tow Package deal. The Most Loaded Trailer Weight we will tow is 9,200 lbs utilizing a weight distributing hitch.
From the Proprietor’s Guide
This exhibits the Most Trailer Weight for a Weight Carrying Hitch is 6,000 lbs with a Most Tongue Weight of 600 lbs.
The Most Trailer Weight with a Weight Distribution Hitch is 9,200 lbs with a Most Tongue Weight of 920 lbs.
Automobile Weight Decal
This exhibits the utmost Gross Axle Weight limits of three,300 lbs for the entrance axle and 4,250 lbs for the rear, which mixed is 7,550 lbs. Nonetheless, word that the Gross Automobile Weight Ranking is 7,300 lbs, which is lower than the sum of the axles. That is correct as a result of the max weight depends on the body, engine, transmission, brakes, and so forth. If one axle is at its max then you definately can't load the opposite axle to its max. To be trustworthy with you, I just lately observed that GVWR is lower than the sum of the axles, and a few of my earlier posts on weight are inaccurate as a result of I didn’t know this.
Now the GVWR of the Expedition is 7,300 lbs and the Most Trailer Weight is 9,200 lbs, which added collectively is 16,500 lbs. However Ford’s Mixed Gross Automobile Weight Ranking is 15,000 lbs. We have to understand that a part of the 9,200 Most Trailer Weight is carried by the Tow Automobile, not the trailer, which is the Tongue Weight. However even when we calculated the mixed towing weight with the utmost capability and a tongue weight of 920 lbs the Mixed Gross Automobile Weight can be 15,580 lbs, which is 580 lbs over Ford’s CGVWR of 15,000 lbs. Ford is telling us you can not tow with the Expedition at its most and on the identical time tow a trailer rated at Ford’s Most Trailer Weight Ranking.
Complicated, isn’t it?
This chart I created may assist:
Right here is the Trailer’s Weight Capability Decal
Most Trailer Weight (GVWR) is 9,000 lbs, which is 200 lbs lower than what the Expedition can tow. It has two axles that mixed are rated at 6,000 lbs every or 12,000 lbs, however that exceeds the Most Trailer Weight ranking (which is an efficient factor IMO). Additionally the unique tires, ST225/75R15D, are solely up to 10,160 lbs, which remains to be extra that the GVWR of 9,000 lbs. So 9,000 lbs is the utmost — all the time go along with the trailer producer’s specification for Most Trailer Weight.
There is no such thing as a specification for max tongue weight on the decal, however the coupler is stamped with 1,250 lbs and that's method, far more than I'll load it.
Okay, I’m 66 now and the reminiscence isn’t what it was once. Misplacing my morning espresso isn’t an enormous deal, I simply get one other cup and fill it up. Likewise, I usually misplace my cellphone, however that may be a good factor as a result of the rattling gadget can’t hassle me if I can’t hear it ring. At one time I knew what tongue weight was, however I had a “senior second” once I learn the decal on the Expedition’s hitch receiver.
At this level in some way 920 lbs Max Tongue Weight for a Weight Distributing Hitch obtained translated and deposited into my greying mind because the max weight the receiver may carry. This was bolstered by many individuals on the Web, so known as specialists, who wrote the identical factor. I wasn’t within the Weight Carrying limits as a result of I don’t plan on towing something with one of these hitch.
I don’t understand how a lot the Weight Carrying Hitch weighs, however the Equalizer is true round 100 lbs. As well as there are two brackets which can be completely bolted to the trailer’s body they usually don’t weigh a lot.
No, V-5 isn’t some type of German Rocket. Whereas working with my hitch elements I observed the next references to V-5 and VESA-5:
So what’s VESA-5 or V-5?
It's an acronym for Automobile Gear Security Fee Regulation VESC-5 that units the
That is the doc and testing customary utilized by automobile producers, hitch producers, coupler and trailer producers.
Why is that this necessary?
This regulation defines tongue weight together with all the things related to tow autos and trailers. Right here is the part that defines tongue weight:
The language is fairly reduce and dry – the load of the hitch is just not thought-about to be a part of the tongue weight and is added to the cargo weight of the tow automobile.
Listed here are hyperlinks to VESA-5 and the just about equivalent SAE 684 (Society of Automotive Engineers, which is a company that units business requirements, amongst different issues).
So for my 2012 Ford Expedition, which has a V-5 compliant hitch receiver rated at a most tongue weight of 920 lbs, the load of the Equal-i-zer hitch is added to the cargo weight of the automobile. In different phrases, when figuring out the load of the tow automobile, the hitch needs to be included as cargo weight. It additionally signifies that the receiver is designed to hold 1020 lbs (the max tongue weight, plus the hitch weight). Take into account that most weight distributing hitches weigh round 100 lbs.
That is necessary as a result of once I arrange the Equal-i-zer I had the load of the tongue plus the hitch proper round 900 lbs, with a complete weight of the trailer at 8,500 lbs. In my thoughts, the tongue weight was 10.5% (900/8,500) however in actuality it was 9.4% (800/8,500) and was too low.
One of the best ways to weigh the tongue I've discovered is the Sherline Scale.
I used a 6,000 lb Equal-i-zer on our 2006 Niagara Tent Trailer and was thrilled with its efficiency. I wasn’t proud of the Equal-i-zer towing our Milan journey trailer. I’m positive a part of the rationale was as a result of tongue weight of 9.4% being under the specs of 10% – 15%, which was specified by Ford, Equal-i-zer, and the Milan’s producer. Nonetheless, even when I upped the tongue weight to 920 lbs. or 10.8% I wouldn’t have been comfortable. It's because the Equal-i-zer additionally controls trailer sway — which means that when wind or a passing huge rig passes you, the trailer will sway and the Equal-i-zer and related weight distribution hitches will, at that time, try to regulate the sway. Trailer sway can doubtlessly develop into a devastating drawback, and when a trailer begins to sway it occurs so shortly that given the appropriate set of circumstances it could develop into lethal. The ProPride hitch I purchased is completely different. It eliminates trailer sway. A trailer can't sway when the ProPride or the same Hensley is used.
Projection Level Trailer Hitch
Two corporations make one of these hitch; The Hensley Manufacturing Firm and ProPride who makes an improved model of the Hensley Arrow. Each hitches had been designed by Jim Hensley. For the story, you possibly can examine it right here:
I purchased a ProPride Three years in the past.
Because the ProPride hitch weighs virtually 200 lbs and it's a weight distributing hitch, then in line with the VESA-5 Regulation I can connect a 920 lb. tongue weight to it and tow with my Expedition, which might imply 1,120 lbs can be carried by the Expedition’s receiver.
Effectively, no I can’t.
The truck producers design their autos and adjust to V-5 assuming a “customary” WDH. The most typical WDHs are made by Reese and Equal-i-zer and weigh round 100 lbs versus virtually 200 lbs for the ProPride.
One factor I did, utilizing my contacts within the automotive business, was contact some engineers at three corporations to see if I may get particular data on the testing process and what weights they used for a WDH. As I anticipated, I didn’t get any actual solutions and was referred to verify the Proprietor’s Guide or contact considered one of their sellers. That is fairly customary, given the affect of their authorized departments. None was accustomed to the Hensley or the ProPride and that didn’t shock me both. I think the full variety of each hitches mixed which can be in use is greater than seemingly underneath 10,000 items versus the hundreds of thousands of latest vans and SUVs which can be bought annually within the US.
However as mentioned earlier, I've decided that my receiver and automobile are rated to hold 1020 lbs with the load of the hitch and the tongue mixed. So I allocate 100 lbs of the hitch to the tow automobile capability and the opposite 100 lbs. to the tongue weight. Because the ProPride doesn’t work something like a standard WDH the design can be added to the tongue weight. That is my conclusion and it really works out nicely when towing our Milan journey trailer.
I've pushed in some fairly extreme winds with out incident utilizing the ProPride. Our Expedition has a system known as AdvanceTrac® with Roll Stability Management™ (RSC®) that additionally contains trailer sway management (word: the sway management doesn't eradicate sway, it tries to mitigate it if the pc detects trailer sway is affecting the automobile). This method has been activated Three occasions whereas towing, and every time I used to be rounding a curve a bit quicker than I ought to have. The Proprietor’s Guide warns that if a flip is taken too quick the sway management will activate. When precise extreme trailer sway happens the system, using AdvanceTrac® and RSC®, will activate “and assist scale back trailer sway by making use of brake power at particular person wheels and, if needed, by decreasing engine pace.” With the ProPride, I'm not going to have sway.
Calculating what you possibly can actually tow and the way a lot the tow automobile can actually weigh looks like a frightening activity. However the data wanted is available. As well as, take this into consideration utilizing our Expedition for example. You can't tow if the tow automobile is maxed out in weight and the trailer can be at max weight on the identical time.
If we drive our Expedition at its Max Weight and the Trailer at its Max Weight, the mixed weight can be 15,580 lbs or 580 lbs greater than the Mixed Gross Automobile Weight Ranking.
The final time I weighed our arrange, which was final September on lengthy tenting journey, that is what it seemed like
Of you possibly can simply skip all of this and spend loads of more money and purchase a tow automobile that's a lot bigger than you want. The selection is as much as you.
