Hi, been reading the forum a bit, and I see lots abot 250 vs 350 SRW, however, I can't seem to find info about SRW vs DRW.
What are the real world numbers for these two after wife, kids, dogs, fuel, etc? We have a 5er so those are the types of numbers I am looking for. Current trailer is irrelevant since its a light-weight and any SD will handle it, just thinking about the future...
I have an F350 SD Lariat SRW with a 3.55 rear end. I tow a 13.5K 5th wheel and average between 9-11.5 MPG at 65 MPH. Above 65 and the mileage slips off considerably. Not sure if I needed it or not, but I added the Timbren suspension system....which is essentially two industrial bumps stops. I'm very happy with them. At any rate, since the truck is also my daily driver....a dually is just too wide for me. If we decided to full-time...I may get a dually..but for now we are quite happy. BTW, I've gotten as good as 19.5 without the trailer.
Another little thing to keep in mind is that with the DRW, rotating tires is a PITA. The local Discount tire here charges $60 to rotate a dually, free for the SRW. When you buy tires for a DRW 4x4, you buy all six, even if only 2 are worn out. Needless to say, most people with DRW won't be rotating every 5,000 miles so you won't get optimum wear from your tires.

Just picked up a 2012 350 dually the mileage is great along with the power. Just got the new hitch so haven't towed yet, will test hook-up today.
Traded in an 08 6.4 dually, truck was great. The mileage wasn't my trailer is 14 K I was getting around 6.5 to 8.5 towing.
Both trucks have 3.73 gears with 4wd.
Hope this helps, Wayne
Hello, how many miles were on the 08 dually you traded and did you have any mechanical issues? I ask because I am in the process of buying an 08 F 350 dually with 69,000 miles on it. Only problem was a radiator change at 25,000.
Alex ..... I had No Problems with my Black Pig. The truck was a good one, I did have fuel gel twice but that wasn't the trucks problem. My truck has or had 56 K on it. The truck was loaded too everthing including the Moon roof. I loved the truck but the mileage was terrible.
The new one is unbelievable as I'm getting 11 on a test tow, and 16 to 18 around town. Well we do live in the country. Good luck with the truck.
I had a '06 6.0 350 srw
Now I have a 11 6.7 350 DRW.
I will not tow with a SRW again after this DRW

I had a 2005 f350 drw 6.0 and bought a 2011 f350 srw 6.7. I tow a 14K 5th wheel and the SRW does just fine. It does wonder just a bit more than the dually did but the added power and better brakes on the 6.7 more than make up for that. I dont mind towing my 5th wheel with my new SRW at all.
Thanks Gents. I think I'll stick with the SRW until I retire and consider dragging the 5th wheel around full-time. I can see where the dually would be more stable in the wind, and it likely adds a margin of safety should you end up with a rear wheel flat...but the added width for my daily driver is just more than I'm willing to tackle at this point. BTW, my 5th wheel is somewhere between 13 and 13.5K--and I love the integrated brake controller in the 2011 6.7. Sure, I have to run it a maximum gain....but the truck and the trailer brakes are matched up perfectly. I don't even know it's back there during normal braking. Very sweet indeed. Thanks again.
Like rampinator I traded a 05 dually 6.0 for an 11 f-350 srw cc and pulled my 26' enclosed car hauler with both and honestly can tell no difference other that the 11 has more power and better brakes. If I was pulling a fifht wheel I would have concidered a dually. Steve
