Mileage and Gear ratios. SRW or DRW

[benstefa1@yahoo.com]

All,
1. What ratio axles do you have in your tow vehicles?
2. What is your mileage pulling the New Redwoods?
3. Do you tow with a 250,2500,350,3500, or bigger still?
4. Single Rear Wheel SRW or Dual Rear Wheel DRW
5.What motor is in your rig?

I will start --
3.31 Axle
12.5 MPG
F-250 SRW
6.7 liter diesel

The reason I am asking is I am considering moving up to an F-350 DRW.

The last trip I made the ride was smooth the speed was not an issue. The only time I noticed a bounce in the truck was coming off or on a bridge occasionally. I did not notice any sway....
Does a DRW vehicle offer better stability and less sway than SRW? I am afraid if I run a 3.73 axle on a DRWI will lose about 3 MPG?

I have a 2006 Dodge 2500 diesel. I am not sure of axle rating, but I averaged 11.5 MPG from Waco to San Antonio and back to Waco. I have had a dually and went back to 2500 because the wife did not like driving the dually. I personally have not noticed that much difference in the ride while pulling with the 2500. Bottom line: it is personal preference, driving habits and where you are.

I pulled a Jayco 40' Designer to San Antonio and the 36RE back. The RW weighs in about 1K heavier than the Designer.

I have a 2011 DRW with 6.7 diesel and 3:73 gears with my Montana we gross out at 25143 and we average 10.5 MPG at the speed limit with the cruise on and only 435 miles on the truck. There is no problem with power and driving empty I get 16 to 21 MPG it just depends on speeds and traffic.

[mhs4771]

2011 Chevy 3500 Dually, 3.73, Duramax/Allison pulling our Montana (weighs just over 14K) avg 9.5 to 11 depending on traffic, weather, and terrain.

We have an 08 F250 Crew Cab XLT with 6 speed auto and 6.4 Diesel with SRW and 3:73 gears. 18K SuperGlide.We just turned over 15,000 miles.
We were _averaging 19.7 mpg when we first bought the truck new..Towing a 36 foot Alfa Sun we averaged 16.2 mpg towing...Then the factory had a recall about the ECM and Pcm which they replaced and the mileage is now about 14.5 towing and still around 18 when not . We did and still will use cruise control and drive at 75mph usually about 5 over limit..Crusie works great.

The 04 1/2 is when Dodge went to the 325hp. up graded injectors and pump. going to the banks system, improved the milage. increased the hp and torque. the increase,I beliveis better than the stock 2011&2012get.

Thanks for the xtra info...I'm a school bus diesel mechanic and was just teasing about what the other half might be, but I'm sure you already new that...I guess I don't know enough about the banks system but I'm proud you do and that your mileage is sooooo good

I knew you were teasing. I have recomended the Banks system to many others. I've had it for going on seven years. the diesel runs cooler and better mileage. 335 hp to the rear wheels and 750 lb ft to the rear wheels. I do inspect the u joints at each service. after 133,000 miles, it runs and sounds great.

I had a 1999 f350 DRW 7.3 with the Banks stinger plus system and a gear vender overdrive set up and pulling at 70 with the cedar creek I had at the time I averaged 14 MPG but solo I averaged 12mpg it did not make sense. I hope Gale Banks comes up with something for the new 6.7 ford soon , because when they do I will be installing it.

Banks is starting to advertise a system for the Ford 6.7 in the Diesel Mag

[KR2011]

Is just an exhaust system or a programmer and a complete system?

They started advertising the complete system in one ofthe magazines.....I think it was diesel magazine

[KR2011]

Thanks I'll look for it or I'll call Gale tomorrow.

[BradPAjax]

Do these Diesel systems void the warranty? I just ordered a brand new 2012 F-350 Diesel Dually to pull my 38BR and keep hearing about changing the exhaust and the chip being the first things I should do. I have not paid yet waiting for the VIN from Kentucky so I know she is on "the line". What about extended warranty?
Dumb questions... have never owned a truck... drove lots in my 10 yrs in the Reserve 20 yr ago.
