So Scott Brady the important question is at 260 are you exceeding your personal gvwr?
I found the standard.

I am not a FMV standards guru. Sorry to disappoint.
Now I'm disappointed, because you think my lighting argument has no validity, simply because you don't understand it.So you come back to the payload thing because you realize your lighting arguement has no validity. Good call.

Slightly
Without the gadgets, I am 225. Should probably be 205-210 and working in that direction.
Backpack, sidearm, magazines, boots and clothing, I am 260

Just trying to soften all the gvwr talk. Hoped you got my attempt at humor.
Indeed, you're not. The listings in the Title 49 CFR Part 571 make reference to the standards, but don't have the entire standards in them.
I'm not disappointed, though-- I can't expect everyone to know these things, unless they're actually designing vehicle lighting systems-- such as AEV when they designed their light-shaped toy.
Now I'm disappointed, because you think my lighting argument has no validity, simply because you don't understand it.
Oh, no-- the argument is perfectly valid. AES specs as "upgrades" headlamps that are not upgrades because they do not meet the photometric requirements for headlamps. Essentially, they are charging to remove the headlamps and replace them with light-shaped toys.
As far as the CHMSL, it immediately fails at the EPPLA. It does not pass go, it does not collect $49.00.
I don't need to understand it. This discussion is about the Brute as the Ultimate North American Overland Vehicle. The Brute has the stock headlights and doesn't use the CMHSL you reference. So why does it matter? Because AEV is making money dishonestly? Maybe validity was a poor word choice. Your light argument is irrelevant.
I'll stick with my two door. I hate extra space. . .then they start asking you to move things for them.
You're right they probably extended the frame with recycled aluminum cans because they picked an illegal headlight as upgrade.
The same is true for IPF, depending on the qualifications of the reviewers.Based on the reviews on this site and many others AEV has a pretty good reputation.
We sincerely hope.Maybe they took a shortcut on their headlight supplier, shame on them, but it doesn't seem to speak for the majority of their work.
So throwing out the company because of a shortcut would be like never buying a GM because they sold cars with faulty ignition switches. Or never buying a Tacoma because the leaf springs could rust, break, puncture your gas tank and kill you. Or never buying another Jeep because you could get rearend and explode. I think if we took a look at every company on this globe we find a shortcut they've taken, which means unless you make everything yourself, you are taking some risk, which I am willing to do.
If I went into the car making/car upfitting business, you can bet I'd hire qualified people to do the work. And if I were going to make regulated motor vehicle safety equipment (such as CHMSLs), I'd be sure to make it conform to FMVSS 108 and the apposite SAE standards. Building a CHMSL whose lens itself isn't physically large enough to warrant testing anything else about it demonstrates that they were building this equipment without actual knowledge of what it takes to do it correctly.Are YOU qualified to design and produce everything you use on a day to day basis?
I'll stick with my two door. I hate extra space. Next thing you know people expect rides and then they start asking you to move things for them.
Don't troll. It's unbecoming. What it means is "they messed up an important road safety detail big time". If they mess up something so simple (yes, it's actually quite simple to determine if a headlamp is decent or not, and a company that charges $80K+ to bolt stuff on an existing car almost certainly has the money to do a little research).
The same is true for IPF, depending on the qualifications of the reviewers.
We sincerely hope.
It's how those respective companies handle such things that will speak more for it than having never made the mistake in the first place.

How about we take numbers from an actual Brute?
Be careful with the "assumptions"

This is the actual payload sticker from the Brute outside my office. GVWR is 5,700 pounds.
However, it is important to note the GAWR too.
The front GAWR is 2,775 lbs.
The rear GAWR is 3,200 lbs.
2,775+3,200= 5,975 combined OEM GAWRs
Another interesting detail is the axle manufacturers GAWRs
Dana 44 Dana/Spicer rating= 3,500 lbs.
3,500x2= 7,000 lbs.

This is a photo taken of the actual weight of the Brute, with a few things in the back (recovery kit, small tool kit, tarp and ratchet straps). The critical thing to note is that this vehicle is essentially "built", which means that it has front and rear bumpers, winch, aux. lights., sliders, suspension, water tank and 37-inch tires!
This Brute actually weighs 5,160 lbs. The 260 lbs. on the slip is me getting out of the vehicle from the initial weigh in, and taking my backpack and firearm out with me.
So, there are multiple results to consider here:
Most conservative (GVWR): 5,700-5,160= 540
Conservative (Combined GAWRs): 5,975-5,160= 815
GAWR limit (Combined Dana 44 rating): 7,000-5,160= 1,840
What does AEV say about payload, based on their research and engineering review? ANSWER LINK HERE

I went through all of this (painstakingly) with EarthRoamer and the Chrysler engineers when I purchased the EarthRoamer XV-JP. We had transportation lawyers involved and everything, just to make sure I wasn't going to be liable driving down the road with a 6,200-pound, $140,000 Wrangler. The conclusion was definitive, which was not to exceed the combined OEM GAWRs, plus 10%. I felt comfortable with that. So the upper defensible limit of a Wrangler running down the road is 6,572.5-pounds. AEV will never endorse that and neither will EarthRoamer. I certainly do not endorse it, but that is what our research resulted in.
The XV-JP I took over the Rubicon
Our XV-JP, in the jungles of Guatemala. Just over 6,200-pounds for that trip! Flawless.
Summary of Payload:
The range is 540-pounds being most conservative based upon the actual placard and 1,840-pounds being the hairy upper limit of defensibility. The best number is right from AEVs FAQs, which is 892-1,000 pounds. That is more than enough payload when you factor the vehicle already has most of the heavy bits installed and four 37" tires as unsprung weight. The Brute is not AT GVWR, that is fact. If people want to split hairs on the 892-1000 pounds from AEV, have at it. There is more than enough supporting documentation and precedence to justify those numbers.
