I don’t think anyone would argue that a DRW is more stable at carrying a TC but let’s hear some thoughts when comparing “apples to apples”For example let’s assume trucks are both new Ram 3500 4x4 diesels. 1) Ram SRW SB with a payload off approx 3800 lbs carrying a Lance 855 S which is 8’11” with a slide and a wet weight of 3800-4000 lbs. and approx 2’ of overhang. 2) Ram LB DRW with a payload of approx 5000 lbs carrying a Lance 1172. 11’11” and wet weight of at least 5000-5500 lbs. and almost 4’ of overhang. Both trucks will be at or slightly over GVW rating but assume within axle and tire limits. I’m sure if you wanted to get scientific and calculate wheeelbase, cog, weight, overhang, roll moments etc you would get a scientific answer, but what do you think seat of the pants feel would be?Would a SB truck at its GVW be as stable as a DRW at its GVW?To add more thought, add a few hundred lbs of hitch weight for towing.

Wide stance provides more stabilityLongbed provides better rideLongbed DRW....hard to beat when AT/OVER GVWR carrying a TC

DRW will feel more stable even when you pull a trailer with 100 lb tongue weight.But there is lot of variables here. First seem you are comparing taxable GVW. Camper doesn't ride on taxes, but on actual truck, so you have to compensate for differences. Than tires make huge difference in handling heavy loads. Than you don't calculate COG placement on campers. When 8-11" camper will put some load on front axle, the 11-11" camper will take some weight from front axle.

The acronym you want is "GVWR" and no, an srw will never be as stable when overloaded.

^ Spot on.Best statement I've heard in a while....Camper doesn't ride on taxes, it rides on the truck.Comparing apples to apples 100% except srw or dually, spring rates the same, the body roll of the truck body and camper will be identical from the springs up. Width between springs are the same.The additional tire capacity of the dually(not the moment arm of the wider track rear end) will provide greater stability via less give in the tire(s).Now of course all the other stuff Kayteg said also will come into play as well in anything other than a controlled experiment where all the parameters are the same.

In theory if you put soft enough tires on the DRW, it could actually experience more roll than a SRW with stiff tires. The reality is you have 2 tires per side plus more width so it would be difficult to make that happen practically.This all assumes someone hasn't messed up the suspension with something like inboard airbags pumped up too high. I once ended up behind a guy with a similar sized camper to mine but on a DRW. He was all over the place tipping back and forth while I felt barely any movement. He eventually pulled off since he was holding me up. I don't know what the issue was, but his DRW was clearly body rolling far more than our SRW.

DRW hands down has safer, more stable feel.

Most modern campers are way too heavy for a SRW. If you're using a SRW get a travel trailer or 5th wheel.

Just my experience and humble opinion.

I am at 13X DRW will be FAR more stable, and only a bad bit harder to park. We are full time 5er's and it is our only vehicle.

I was just looking through Ram body builders for 2018 and I don't see any SRW rams with a payload of over 4000 lbs. they don't list any 19 4x4's yet.

most of the 2018 dually long beds are rated at payload around 5600-5700 with diesel.

If your truck comes with a "camper slip" you will see the number lower. they take payload - about 150 lbs for each of the 6 seating positions so your allowable camper load slip will be 800-900 less. (I see they never did Camper guides for the ram 3500's in 2018 on line, and my 2018 did not come with one and factory could not produce it).

the Lance 844 is rated at 3967 lbs wet on truck camper mag.
the lance 1172 is rated at 5213 lbs wet on same site.

This is not apples to apples.
If you want any data about SRW at it’s rated GVWR (which is an artificial number to begin with) vs. DRW at GVWR, you can’t throw in other variables that affect the outcome such as making one a shortbed and the other a long bed.
And it’s not like everyone doesn’t know the answer.

I forgot to add, I went from a 2006 Ram SRW 2wd with a Wolf Creek (3000 lbs) and I was dead on my rear tire rating with normal loading, until I hooked up a trailer.

to a 2015 Ram 3500 4wd tradesman dually (with 4:10), Than to an Arctic Fox 990, than to a 2018 Ram 3500 laramie 2wd dually (3:73)

The 2015/2018 are different trucks from the 2006. but it was a big difference going from a SRW to a dually.
Than I added Lower staple loads to to the 2018 to bring it back up to level in the rear loaded and the sway/ability to carry load got even better.
all 3 trucks has the BigWig sway bar added to them.

I started with a Arctic Fox 811 on a Ford F250. With the just the camper package and 18" wheel option, it safely hauled the camper with wheel capacity even though it was over stickered RAWR and GVWR. I also towed an 8000 lb 20' enclosed trailer behind this truck camper. Although I was able add Torklift upper StableLoads and Firestone airbags to keep the load level, I had to be extremely diligent on how I loaded the camper and trailer so I would not exceed rear wheel capacity even though handling was just fine. After upgrading to 19.5" wheels, I no longer had wheels holding back my rear axle loading, so I added the Torklift lower StableLoads and Rancho RS9000XL adjustable shocks. This allowed me carry 8000 lbs on the rear with 4500 lbs on the front when I had my trailer in tow for a total of 12,500 lbs GVW and 19,500 lbs GCW. This combination did well all over the western half of the US until we decided a bigger camper was in our future.

I upgraded the truck to a Ram 5500 for the future use camper upgrade. This truck did not need any wheel or suspension upgrades and the camper would not even compress the spring pack enough to touch the overloads until I hitched up the trailer too. The stability was about the same as the upgraded F250, but ride quality was actually harsher - This was a case where I had too much truck for my load.

Once we upgraded the camper to a Host Mammoth the ride quality got better and stability still did not suffer. I see no way a SRW could carry a camper of this size without causing handling or material issues.

Since upgrading the camper, I have added 400 lbs of enclosed boxes and 600 lbs of batteries to the truck and 300 lbs of batteries to the tongue of the trailer. To keep this combination level, the Ram 5500 has Torklift upper StableLoads. It is still under all sticker and wheel ratings and handles fine when loaded at 18,000 lbs GVW and 26,000 lbs GCW.

My take on the DRW/SRW debate is that you can upgrade a SRW beyond the sticker safely if you research the weakest parts and replace them. There are things you can do to a DRW to help handling a load, but you will find that GVWR and RAWR are closer to real component limits and you will not be able to increase those as much as a SRW that is limited by wheels and soft suspension.

For carrying our Citation 9-6, in 2007 I switched from a SRW LB to a DRW LB and the difference in handling was like night and day - while a SRW will work, the dually is the right tool for the job.

^ Never would have guessed that this tread would have gotten off topic.
The OP didn’t even ask a well thought out question. “How does the handling of a little truck with a little camper compare to the handling of a big truck with a big camper?”
That’s like asking which is better, bacon or sausage with pancakes.....sort of relavent because they’re both breakfast meats that come from a pig, but not directly comparable.

If you want apples to apples, use bagged concrete for the weight instead of campers.

43 90lb bags of Sakrete in the SRW
62 90lb bags of Sakrete in the DRW

Then take them both on the Nurburgring.
