What you're calling the "dynamic weight" is inherent in the static value they give you. They don't need to give you any "dynamic weight." The average vehicle owner would not know what to do with it. (Heck, half the people don't understand simple "weight.")

You don't see bridge limits that say "10 tons - but only 8 tons if you think you might hit a bump on the bridge."



As a crane operator, you may have to had to deal with something like "dynamic weight," (I'm guessing it has to do with the load swinging from the cable) but your average vehicle owner can't be expected to do that. It has to be built-in and it is.
One more time and I shouldn't waist my time. I never said anything about engineering. I just stated what the little plack represents. No wonder most y'all fuss at each other on these forums.

And you ended your blurb saying the plaque is "misleading fo sho." Now you've implied that people shouldn't read/use/trust the plaque.

It's not misleading. To use your words, it tells you the "static weight" that the engineers have determined you can safely tow at legal speeds, when it becomes "dynamic weight."

How is that "misleading?"

Perhaps, but interdependent and certainly not mutually exclusive. In general, the more pounds in your truck's payload, the lighter your towed vehicle should be. Which is why I like Polks formula. Manufactures embellish towing capacity, acting like each vehicle is driven by a 150 pound person sans passengers and equipment.

I did not say the static placks are misleading. I stated a lot of information on this forum pertaining to pick ups and trailers are misleading. If you are gonna try and match wits with me get your info straight. I'm done babe. It's just you and judge judy

Guess I'll take the high road on this one.

And maintaining a speed on a grade etc... It doesn't address wind resistance. Nothing about durability is another of my biggest want-to-knows. The SAE J2807 has only been around for about a year anyway. I guess one should ask the dealer if the truck meets SAE J2807, prepare for a blank stare. ha


Toyotas been following the standard since 2011

Take your max tow weight and times it by .75, this is the MAX you should be pulling. At at least this is what I have found.

Ford's towing folks disagreed with that when I asked them specifically what the numbers mean based on the certification testing. If you throw out a number or a percentage - please base it on facts that have been tested and released as documentation by the manufacturer or certifying agency. There is too much garbage on this forum.

Well now let's see: I'm definitely not an engineer but I'm very technically savvy. I follow established procedures, policy, and specifications because people much smarter than me have documentation to support their position. The max weights for the TV and tow rigs are established and documented so I don't need to guess or be concerned if I'm overloaded and I can be sure I'm running well within my load limits. When I change TV or change rigs I use the weight programs and charts to make sure I'm going to be within my weight specs for my tow combination.

The weight police and lawyers are out there and I know as long as I meet the legal limits if I have an issue I'm confident that my insurance coverage will support me.

You can chose to turn a blind eye to max weights and just take off without having any problems but maybe not. I can assure you if you have an accident that hurt's someone with a over weight plated tow combination you'll be supporting another group of people for a long long time.

Wow! This thread has been heating up since 2011. BTW does anybody know where you can get your rig weighed individually at each wheel. I want to make sure I am not overloaded left to right. I know Escapees does it in Livingston Texas but its far off the beaten path and kinda inconvenient.
