The truck configuration and trailer info is in the OP.
It's a gasser, not a diesel.
The Roadmaster suspension raised the truck up a few inches unloaded and leveled out with the trailer loaded. Not ever towing a fifth wheel before I have nothing to compare the Roadmaster to, ie... Timbrens or Air bags, but I can say the truck rides nice while towing and there is a big improvement in the ride when not towing. The installer set the system on "40", meaning the truck has 40% more load capability. More than a F350.

I simply cannot tell you how fast your creditability slide down hill after that statement. You've become "that guy."

As kfxgreenie noted that is an awfully good payload for a modern diesel 3/4 ton. Is that from the door? I was looking at the Roadmaster suspension upgrade. Could you actually tell it was doing anything? Was it this setup;

The OP’s TV is a gas 6.2, not a diesel.

I guess I missed something in my research.
The enhanced suspension along with the difference in payload (in my favor) because the truck is a gasser (FFV) and 2WD add up to enough truck for the pin weight of the trailer and the hitch package.
Adding 40% to the trucks payload makes it more than any F350. Correct?
I could be wrong and really trying not to be "that guy".
The truck tows and stops the trailer. While it is not "effortlessly" the RPMs and gauges and handling are normal.
I appreciate the help available on here versus a pi==ing match on credibility.
Thanks

I wish you the very best. I think you are stretching it, but, it's your call. I know how alluring those new trailers and floorplans are.....just spent the afternoon 2 days ago looking at 5vrs. And DW hates them....but, when I brought the brochure and emphasized a front living area.....she ACTUALLY looked at the floorplans!! Ahhh. how the RV circle works! You WILL be working that engine!

This is from the FAQ section of the Roadmaster website: https://activesuspension.com/faqs/

"Will RAS increase my payload?
RAS could increase payload, but it is not recommended to increase the manufacturers rated payload GVWR, as overloading can cause damage to the frame and other under body components. However, with a RAS installed the vehicle will now be able to carry manufacturers rated maximum loads while reducing rear sag and bottoming out."


There is a heck of a lot more to payload, GVW and towing than "installing something so the rear end doesn't sag any more".

I thought the sticker on the drivers door was the final answer no matter what you add.

The Roadmaster doesn't do ANYTHING to increase payload. Sort of like adding an add a leaf, and if looking at the website, that is essentially what it is. Doesn't do a thing to increase payload.

We haven't seen the payload from the sticker on the door; that would be enlightening because that is the final number...Roadmaster or not. To think that adding some "gimmick" to your springs increases your payload by 40%.....you need to be more informed and do more homework. Your'e making a mistake IMO. But then again, I travel all the time and see folks doing it daily...unfortunately.

Laredo, by "that guy" we are referring to those who hook up a half-ton pickup to a fairly large Cougar and try to tell the inquisitive public it is safe because the dealer said it is. Keep the examples going up from that point. We as members see a large group of people every year posting here (and other forums) who have a i.e. 2011 GMC 1500, buy a used large Cougar, add airbags with onboard pump, LT tires, additional leaf spring and head down the road with a smile on their face.
"That guy" is the one who now believes his F150 is better than a F250. It isn't so and he won't be able to be convinced (by knowledgeable people) that it isn't so. No p*****g match, but do you see where your add-on accessory matches this description?
I'm not telling you not to tow with your setup. What I'm saying is you need to run through your neighborhood CAT scale and see firsthand what the results are. Then you decide if your rig is safe.

From the OP:
TV- 2016 F250 CC Lariat SB 6.2L 3.73 2WD
Roadmaster suspension upgrade Payload 3126 lbs.
TT- Laredo 350FB Pin 2085 lbs. Dry 11,230 lbs. Cargo Cap 1770 lbs.


The truck payload is 3126 lbs. Roadmaster will improve handling of that 3126 but will not increase the payload.

The trailer EMPTY pin weight is 2085 lbs. Add 80 lbs for 2 batteries and 60 lbs for propane and the pin weight is 2225 before adding any cargo, water, or spare tire. Now, to the truck, add 150 lbs for a hitch, then potentially add a blue tank, generator, tools, tonneau cover, etc and you can easily approach the maximum payload with one passenger weighing 150 lbs. (but my DW is skinny so I've got extra weight) Don't forget her purse, the cooler in the back seat, coats, umbrella, etc... They all count too.

Now for the Roadmaster addition. Yup, the weight of that "iron" also adds to the truck weight (reduces payload by the amount the parts add to truck weight).

So what was a truck payload of 3126, with 100 lbs of "roadmaster" is 3026, with hitch is 2876, with 50 lbs of tools is 2826, with 150 lbs DW is 2676, then all those "goodies" (TPMS, maps, rear view camera) deduct from that as well.

Now for that 2085 lbs pin weight (that turned into 2225 empty with batteries and propane) with 1000 pounds of cargo (food, camping gear, wood/plastic blocks, chocks, jack, awning mat, grill, etc) and you're looking at a trailer that actually weighs 11230 (advertised dry weight) + 80 + 60 + 1000 = 12370 before any water is added to any of the tanks. Figuring 15-25% pin weight at 12370 comes to a "real world pin weight" somewhere between 1855 - 3092.

When considering the "real world payload" around 2675 and the real world pin weight (20%) around 2475, which leaves around 202 lbs "to play with" before you reach the truck GVW of 10,000 lbs. Your truck "may or may not" be technically overloaded. Only a trip to the CAT scale will tell you for sure.

Now, as for Roadmaster's "makes it 40% more payload than a F350.... HOGWASH. Your truck front axle (if a regular build) is rated at 4400 pounds and the rear axle is rated at 6100 pounds. The F350 (regular build) front axle is rated at 4400 pounds and the rear axle is rated at 6730 lbs.

While some people say, "Ford uses the same axles, bearings, brakes and frame, so a F250 is really the same as an F350." the Ford Build data (downloadable from the Ford website) rates the vehicles differently and doesn't include any footnote indicating "they are really the same"....

Going to a CAT scale will tell you what you really need to know, load up the Laredo and go find out if you need to visit your local truck dealer or not. But the Roadmaster "helps with handling, but not with payload".....

OK,
Great feedback from folks who care and have been there. That's solid.
I did go to the scales on the way home after fueling up. I guess those numbers would help move things along here. I had "the inventory" from my traded in TT. Most of that transfers, tools, jack,pads,bug spray ect...But there is room for some weight to be cut. And it will be.
Front Axle:4220
Rear Axle: 5638
Trailer Axle: 9820
Gross Weight: 19678
GVWR: 19800 (The RAS is not in this figure and will not be)

And thanks for the real info on the RAS. Not really wanting to trade the truck,but a choice is becoming more clear with each post
I know the numbers are close to max and like anyone else, not real comfortable near the edge.
Will have to see what the next move is.
Thanks again, appreciate the help. This community (RV blog) is one of the most genuine.

Check the information decal on your driver's door post for the front axle code. Many (not all and maybe not yours) 2016 F250 gas models were built with 3800 or 4100 pound front axles. If so, your truck may already be "in the red"... The 4400 pound front axle rating is for trucks equipped with the snow plow, camper or HD suspension packages.

Some real world numbers scaled on our return trip from Florida, Laredo 325RL Loaded heavy with 250 lbs of extras (additional to normal items), 2 adults, dogs, 1/2 tank of fuel, empty 5th wheel holding tanks. The base truck weight is 1 adult, hitch, and full fuel tank. By extra's there were potted plants in the shower and her apparel decorating equipment and supplies scattered throughout the 5th wheel and bed of the truck.

The dry weight of my 325 RL is 11,180 and GVWR is 13,000 about the same as the OP's, and the 350FB should balance out about the same.

Had I thought about it, emptying the 12gal hot water tank would of shed an additional 95 lbs. Something to think about. I also have a MORryde sliding tray in the basement that adds 100+ pounds of dead weight. (it is nice)

11,260 Truck on scale
8,200 base truck (previous scaled weight)
3,060 Cargo in truck and pin

21,580 GCW (all on)
11,260 Truck and pin and contents
10,260 Laredo Axle weight /2 =5,130 lbs on 6,500 rated axles

I posted this to show the OP he could stay within his numbers, NOT to start a discussion of my numbers.

Well within GVWR of 10,000# even if just.
That said there is not a big difference between an F250 and a F350 SRW, the biggest difference in rear axle rating is likely tires! If you feel like you are pushing your F250 then best to go to a F350 DRW.
Currently your biggest issue is a gas engine with 3.73 gears.

JRTJH, the sticker is 4400 lbs. It is a Lariat package. Not sure if it is a snow plow option, but I do not expect to use that in South Mississippi. Although we did officially get snow this year.

Frank G, thanks for the tip on the water heater.I assume my axles are the same rating. Been trying to find that info. If I may, what truck are you towing with?

rhagfo, For now the gas engine and the gearing is working. Not a ball of fire going down the road, but enough power to cruise,pass some slower vehicles and still maintain normal temps and RPMs. I did check on the possibility of the 4.30 gearing. The whole package (at the dealer) was about $2K. With that rear end gas mileage would be brutal.

I appreciate the feedback. My experience has taught me that those who say "I got this,I got this,I got this" usually get it. Right between the eyes. So I am asking and getting great advice.
Thanks

JRTJH called it... front axle is the problem
My 2017 F250 has a payload of #3620, with front axle rated for #4100 max. So if yours is #4400 you may have had snow plow option and didn’t realize it. Hope it works out for you. I was hoping for a fiver also.. hoping my truck could handle one with a max weight around 10500. Mine is gasser also

I just can't imagine running so close on weight that it requires this. That's like saying "honey don't feed the dogs and make a salad for lunch as we're towing the camper today."
