I'll settle for a SRW until I need a dually .... for me that means overloading my truck on occasion but I'm ok with that.

In reply to the question about distance, Per year i would say we would be in that 1500KM to 2000KM max range total. We pull two decent hills on the way... were on the prairies so certainly not mountains! but there is one hill that gets me down to 3rd or 2nd gear with the 5.9. WHen i had the 15 - 6.7 with aisin it completely anihilated that hill with the same load.

Its always nice to chat with you guys/gals about this sort of info, you could call the dealership but you would get the "pamhplet answer" i consider myself experienced when it comes to towing, ive always been an overkill kinda mentality. However if an SRW would fit the bill i think that would be my next move.

Additional braking power?
Maybe you can expound on how a srw vs a dually (same truck/model, apples to apples) has different braking power. And don't go down the less tires = less braking power. I'd challenge the ability to lock up the wheels on a srw with a big load in the back.

That said, I'm the antithesis of the weight cops on here and could or would tow virtually anything able to be towed with a dually, with a srw provided it wasn't seriously overloading the truck chassis.

BUT, if there was ever a case for having training wheels on a pickup truck, towing a significant set of doubles is it.

So you have a stock 3rd Gen that you need to stripe the tires to see if it's moving when pulling hills and you're worried about srw vs drw? Sounds like you're a rolling road block as it is. SRW = no problem if you're holding up traffic every time you hit the road.

Call the dealership? You’d be lucky if any of the dealer”s salespeople knew what “payload” was.

2nd gear is hardly a road block, I say drop that 5.9 into second and let er eat. Buy a new truck after prices go down. When you do just get a SRW.

Yes the two extra tires on the ground makes a huge difference when braking. BTDT. The dually will have significant more braking power that you will notice from the drivers seat.
In the OP's scenario the only significant reason to go dually would be for better braking. A SRW will have adequate payload.
Since he's double towing installing disc brakes on the trailer would not be a bad idea either.
You don't realize/feel how bad the electro magnetic brakes perform until you compare them to disc brakes.

What’s your definition of driving too slow? OPs trans, 1st is granny gear and 2nd is good for maybe 20mph at redline.

Lantley, you’re gonna have to expound on how 2 more tires = more braking power.
Because I fail to see how it does.
Not that a dually isn’t super preferable for what the OP is towing, but the limits of traction on the srw hammering on the brakes won’t be realized except maybe on gravel or snow with a lot of weight on the rear axle.

The actual brake disc area of a DRW of same year model is just marginally larger than that of a SWR, and actually locking the rear brakes on either is nearly impossible when under load. If you could actually lock the rear wheels on both then the extra braking goes to the DRW.

In the OP scenario.....nothing short of a class 6 or larger would significantly shorten the braking distance. Anyone relying on the tow vehicle to stop a heavy load are pretty badly mistaken.......the trailer brakes should be the primary stopping component for the trailer! Anyone doubting this, just hook up to about 20K pounds, do not connect the wiring harness and do a panic stop from about 60 mph. I think you’ll gain a healthy respect for the benefits of good trailer braking and the inability of a pickup truck to quickly stop said load! memtb
