Payload difference between SRW and DRW
Good morning folks,
Question: On the 2023s, other than the obvious difference between the DRW and the SRW F350s, what makes up for the significant payload difference? Does the DRW have different size axles, brakes, springs/suspension?
Has anyone converted a DRW F350 to a super single?
Thank you for any info!

I want to use a slide-in camper—all of which seem super heavy, especially when counting the wet weight. I have had a 2002 CC DRW 4x4 with a lance, big boy camper. It was overloaded, and I won't make that mistake again. The new duallys have 5-6K payload, so if I use a 2K camper and all the fixings, I will be about 3.5K in payload and room to do want I want. I prefer to be as close to 1/2 max payload. The truck will handle much better, especially off-road.
Also, I would like to use a "super single" to help with off-road use. I am looking at Super Single Wheels - 1st Attack Engineering.
Many people are doing a 550 and liquid springs but that would add 30K to my project.
Any ideas would be great.

You could also get a CCLB 7.3/4.30 or 6.7/3.55 F350 SRW with the 18 AT or 20 inch tire and get the better brakes and higher gvwr. Supercab too maybe.
Start a thread about 23s. This was the case on the 22s.
Then put a set of 18” Method HD wheels and a 129 rated tire.

Even though the DRW leaf springs look the same as the SRW F-350 leaf pack, I have read that they are a higher spring rate.

Are you set on a heavy camper like a Lance? There are other options like FWC and Scout that SRW can easily accomodate. Cirrus also makes a small slide in that weights about 1500.

What kind of "off-roading" are you gonna be doing with a slide in camper? Are we talking just ungroomed dirt roads, or full on blaze you're own trails crawling over rocks/stumps/ravine/etc?
Why do you want to stay around 50% the payload capacity? Run it at it's rated capacity like it was designed for and add tuned shocks, sway bars and air bags to help with control.
From the limited info, it seems like you really need either a 450+ chassis, or a custom spring/shock setup tailored to the use.

For starters, the DRW only come with a long bed, at least in the Fords. RAM has a short bed DRW, which is basically useless except as a people mover. So you would compare to a long bed SRW only. As mentioned, the DRW has a heavier duty rear axle, as well as highest rated springs and paired tires to support the weight. All three combined gives the higher payload. You would have to go to a commercial tire on the SRW to get the payload capacity of the DRW. Payload is always set by the weakest link, in this case, the tires on the SRW.
Thing to keep in mind when sizing a camper is the CG of it. Since the SRW LB and DRW use the same chassis, CG is important on both. If the campers CG falls behind the manufacturers CG point on the truck, it can cause too much frame flex and break the truck in half. So there is more to it than just the weight of the camper.
