Do I have this math/ understanding right?

[gattorgetter]

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?

Gotta get it weighed and then do simple math.

GVWR-CAT Weight = Weight available for hitch. Assuming you were on the CAT scale with everything you would carry in the truck.
GCWR - CAT Weight = Total available weight you can tow. Same assumption as above.

With that said, my pin weight of my trailer is 2700lbs with no water in the hauler.
After I add 150 gallons of water, my pin weight goes up to 3700 lbs.
After I load my sand car in my hauler, which weighs 2800lbs, my pin weight goes down to 3400lbs (with full water in the hauler).

Of course, this is with me having all the normal camping **** in the trailer all the time.
I am just showing weight changes on big ticket items.
If people have to worry about normal "stuff" putting them over a weight rating, they don't have enough truck.

The horse trailers axle location in the picture isn't indicative of all horse trailers. But can be typical of rear stall units.
Center and front stalls axles can be farther forward. Stock trailers and flatdeck trailers are no different and all can have axles located like any toy hauler/5th wheel rv trailer or bumper pull rv trailers.

My stock trailers axle location isn't like the horse trailer in the picture.

Only way to know how much load difference is to weigh. I've seen some way out there math figures from load brokers and other drivers....but non found what the scale house found.

Yup, the only way to tell for sure. All the rest is speculation.

Not the only way...the easiest way.

Math does work but you have to trust that the manufacturer did his part of the math correctly and then you have to do the math on everything added. In the end it's easier to just take it to the scale.

You might be confusing stock and horse trailers also.
Typicality horse trailers have dividers to help support the horses while traveling, they also have an area in the front for storing tack.

This is a picture of my DD's four horse slant with small living quarters. The pin on this empty was about 2,700#, the axles are about centered under the center of the area the four horses would ride.

Getting new tires before towing home after purchase.

Thank you, a very clear illustration that shows what I'm talking about. Any weight added to the rear of that trailer is going to affect the pin weight very little.

You did make me curious as I live in the midwest, lots of stock trailers and all the gooseneck stock trailers I have noticed all have their wheels very near the end of the trailer, unlike an RV. So I did some online looking and almost without exception the gooseneck stock trailers of any length had their wheels near the end of the trailer.

The reason I mentioned this in the first place was because you stated:

"Its surprising how little weight is taken off the hitch when 4k-6k lbs of bulls are placed back there."

This whole thread was about the hitch/tongue weight removed/changed when loading up the toyhauler. So, when you look at a gooseneck stock trailer wheel configuration compared to a normal 5th wheel toyhauler, it really isn't surprising that very little weight changes, but you can't really compare the two since they are so different vis a vis, the amount of trailer past the rear wheels. Put 4k-6k lbs. of bull at the rear of a normal toyhauler and the hitch weight would change considerably. Which is probably why gooseneck stock trailers are designed the way they are.

LOL....You just like to argue.
..... so you looked on line. Big deal Like I said I own them and I don't have too look online.
"Not all" stock trailers axles are farther back than a toy hauler and some 5th wheel rv trailers.
And not all stock trailers axles are set the same. I chose this particular brand/model because of the heavier axles that wasn't set far back like other brands/models so I could use my 3/4 or the one ton DRW.
I also own and transport cattle and horses and have been doing the dance since the '70s.

My 36' GN triaxle stock trailers axles and a 34' GN tandem dual axle flatdeck are no farther back than many toyhaulers I see parked next to me at truck stops or stock show events or stock sale yards.

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.

Having owned several 5th wheel rv trailers and even more different wheel base bumper and GN and one 5th wheel stock trailers I haven't found this to be true.
All stock trailers don't have the same over hang just like all toy haulers and or 5th wheel trailers don't have the same overhang.
However my point was about a trailer working like a teeter totter which it doesn't.

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.
