My current set up has me 800lbs over my GVWR on my truck (Duramax 2500hd) when I have 2 quads loaded onto my deck with my camper hooked up. The truck doesn't really squat much so it doesn't look like its pushing the suspension to the limits. I have been running like this for 3 yrs without any issues but where I live, they never pull RVs into scales so an overweight ticket isn't really a big concern. What does bother me is what may occur in the even if an accident as far as insurance claims/ liability coverage etc. Has anyone ever seen any horror stories of something like this happening? I should have bought a 3500hd and this wouldn't be an issue. Sadly I'm under half way through paying for this truck so to trade it in on a 3500hd would cost me astronomically as they would never give me near what I owe right now. Am I over thinking this?

I would be most concerned with the weight on the rear tires. Have you weighed it?

I have only weighed the whole truck at once. 10800lbs. Never even thought about the back axle alone. The quads on the deck would distribute a good amount of weight onto the front axle I would imagine.

Overloaded and in an accident , can leave you in a real pickle as far as insurance; if the accident investigation team gives you a ticket then that gives the insurance company an out.
I was ; in my capacity as a MOT inspector for the B.C. government ; involved in a court case , where an individual was charged in a wrongful death suit, and the insurance company had denied coverage, when his overloaded trailer broke loose from his vehicle, and ran into oncoming traffic.

First off spend $10 and get your F&R axle weights.

According to the guys on dieselplace.com & Duramax forums the only difference been a Chevy/GMC SRW 2500HD & 3500HD is rear springs & the rear tire weight ratings.

Was that individual in an RV type trailer, or a commercial trailer?

You do not have to worry about a DOT scale house, they are only concerned with commercial trucks. If you are non commercial (just an RVer) you are allowed to gross up to 26000 lbs. If you do not overload any of your tires, you have a vehicle that can handle the load. Going to a 1 ton truck simply gives you firmer rear springs and possibly dual rear wheels. However in Texas you can not exceed 65' in length for your truck and trailer or trailers.

The GVWR on my truck alone is 10000lbs. When my quads are loaded on my quad deck and then my camper hitch is attached to my receiver, the truck weighs 10800lbs. As much as I would like to think I would be ok.... I'm sure that puts my truck overweight. I'm not referring to my towing capacity.

Add the max load rating of the two rear tires together. DO NOT exceed that!

Overweight by 800 lbs and liability - I wouldn't be too worried, I think it'd be pretty hard to prove unless the LISTED pin weight + 2 quads could easily be determined.

Outside of that, I'd want first enough rated capacity on my tires by a decent margin. And I'd probably do airbags unless the suspension still had some travel.

For comparison, my 2500 Duramax weighs approximately 7000 lbs empty, distributed about 59% on the front axle and 41% on the rear axcle. The rear axle are rated at a shade over 6,000 lbs. Accordingly, I have roughly 3100 lbs before exceeding the rear axle rating. (not considering the crucial tire rating)
Since insurance covers liability due to your negligence, it would be a stretch for the insurance company to deny coverage unless it is written in the contract. As a practical matter, towing slightly overweight is a hell of a lot less dangerous than texting or even talking on a cell phone, fiddling with the radio, or a hundred other distracting things people do while driving. If you listing in order the cause of RV accidents, I doubt towing overweight would be near the top.

Mine is a 2012 2500HD Duramax GFX. The tire max load is 3300lbs per tire. There is no way I'm exceeding 6600lbs on the back axle. But I don't know what the rear axle limit is, I'll have to try and find it on the truck when I get home from work.

My other option would be to remove my quad deck and just carry one quad in the back of the truck and look into something like this unit to carry the other one on the back of the trailer. Not sure if this is a safe idea or not.

Now that you have posted on the Internet that you knowingly tow overloaded, all your options are kinda gone as far as negligence and liability.

The main concern, as was said, is the load on the rear tires/axle of the truck. Can you swap up to a dually?

Change your tires and wheels to higher weight rating. Such as Nitto Dura Grappler LT 285/70R 17 -126R tires; the weight rating is 3750 LBS at 80 PSI. Find rims that are close to this weight rating that will fit your Chevy and run the air pressure that will support the load on the rear axle.
