Got a new 2020 GMC 2500 with DMax.Door sticker says just over 3300 for payload. Tires are 3750.So... manufacture's say hitch weight for xx toyhauler is.... let's say 3500lbs... im guessing that is empty... now if I load 2000lb in garage... the 3500lbs hitch weight could/should be less?

The rear overhang from the axles is far less than the front overhang. The toys just behind the rear axles will not make up for all the stuff you put forward of the axles. And you will put a lot there. So no, your pin weight will not decrease. It will increase when loaded for travel.

I never noticed much difference with my toy hauler loaded or empty. Remember you have to add anything in the truck to that max payload, people, gear, dogs, firewood, etc.

It depends on what you're hauling in the garage. Some people have had their hitch/tongue weight drop too much and resulted in poor handling.

Yep. By the time you add 4 people, firewood, a cooler full of beer, exta gas for the toys....you MIGHT have 2500 pounds of payload left. What's your tongue weight again?

No toyhauler yet... starting to shop again..

Do I have this math/ understanding right? | Good Sam Community

From my research I know that Ford deducts 150lbs from payload for each seating position when they calculate payload. A dealer pointed that out to me and then I verified that little tidbit in the 2020 brochure.
This would be the first time I have heard of ANY manufacturer doing this.... I would love this to be true.
Can you provide a link?

It sounds like the dealers lips were moving..:B

"One thing I learned from loading several hundred long flatdeck trailers with wheeled equipment and pallets/etc...... and dozens of long GN stock trailers is there is no center point like a teeter totter for weight calculation simply because one end sits on the truck. Generally we load calves and first year lighter weight stock in the trailers front....then heavy stock (bulls or cows) over and aft of the trailers axles. Its surprising how little weight is taken off the hitch when 4k-6k lbs of bulls are placed back there."

This is true, but one has to take into consideration how far to the rear those trailer tires are compared to a 5th wheel RV, even a toyhauler. There is a lot more overhang on a 5th wheel, so weight added to the very rear of the toyhauler will affect the hitch weight more than a stock trailer.

The 2020 2500 Dmax has a 6390 rawr with 17" wheels and 6600 rawr with the 18/20" wheels.
I would say your truck has the 6600 rawr which is the lessor of a axle assy/wheel/tire or rear spring pack. On newer trucks the rear spring pack is usually the weak link.

GM specs shows the new and very high GVWR is 11550 lbs for the 2500 Dmax/18/20" wheels. This is where the higher GVWR based payload packages are overloading some 1/2 ton....3/4 ton....one ton SRW trucks low RAWR numbers on certain models when the payload is used in the bed/over the rear axles.
I wouldn't go over a 3400 lb load on the rear suspension...in the bed.
You can always upgrade the wheels or spring pack to match your tires 3700 lb capacity. The rear axle is a 11.5" AAM who rates it in the 10xxx range so the axle assy is no problem.

Well the listed Payload is 3,300# and tires are rated at 3,750# ea.

How about the GVWR, and the rear axle rating.

That and scaled weights of the Truck with a hitch and your family.

I ask the GVWR, as GM seems to be playing games with the GVWR of their 2500's and going beyond the 10,000# max for Class2.

Once a TH is loaded for travel with toys and food, cook ware, stuff, and clothing. the pin will likely a bit more than the dry weight depending on how much stuff you carry.

So even going by tires at 3,750# you could put 7,500# on that axles if ready to tow it scales 3,500# that is only 4,000# for a dry pin of 3,500# you are very close.

I guess my big question is WHY NOT buy at least a 3500 SRW to tow a larger TH.

I need to add that when scaling the TV needs to be ready to hitch to 5er. It needs to be loaded with all passengers, full tank of fuel, all gear you carry in the TV and hitch. We lost about 1,300# off our yellow sticker payload. We went from 5,411# to 4,000# once we had the TV loaded. The sticker payload only includes a full tank of fuel & DRF and 150# driver, everything else reduces the payload!

That's not really such an unlikely thing. Not the theft part, but traveling without the SxS. We take trips all the time without the car in the garage. You definitely want your setup to work whether you're loaded up or not.

I'm still curious to know whether the OP is talking about a 5er or a bumper pull.

Yeah, the stolen was just to head off the excuse that "We never don't take the toys". Theoretically, you could load dirt in the back but will you remember.

I have to believe with a 3500lb hitch weight we are talking about a 5th wheel. At 15% hitch weight that would translate to a 23,500lb bumper pull.

One other issue you may run into is will you ever travel without the toys? Maybe not planned but let's say your side by side gets stolen...now you are driving back with an otherwise fully stocked trailer but nothing in the back.

If the garage is empty, now you have the empty hitch weight plus any weight from household gear stored ahead of the axles. Your empty 3500lb hitch weight jumps to 4000-4500lb.

That would be a bad thing..... But in the unlikely event it were to happen, one could always move weight to the now empty garage.
Depending on the tank layout, some shifting of weight may be possible there as well.
