Mpg towing 2015 Montana 3610 rl Legacy

[dfb]

Finally got on a lot of level ground towing across the country. From Las Vegas to the gran crayon in windy conditions= 8.3 mpg... Oklahoma to the next stop 11.4... Used 5th gear and hit 12.6!!!! For over 200 miles.... Very happy with the 3:42s... The SRW mega cab was nearly as good as the dually!...

Spelling errors here are OK. Do it in the Political area and you get called a dipstick.

Have you weighed the truck rear axle with the trailer loaded ready to travel. Bet you are really pushing the 7K rating.

at 7100 on rear! Over by 100 lbs now...I dump the water out of the water heater and all holding tanks.. Gvwr over by 250 lbs...

Way under gcvwr... This is my reason for asking where the water tank is located.. If it's in the rear, maybe adding water would reduce the pin weight...

I get similar mileage with my DRW and 4:10 gears. Varies anywhere from 8 to 14 MPG depending on conditions towing a similar sized 5th wheel.

I don't think gear ratios make much MPG difference towing a heavy load, mine stays in 6th almost all the time. The 3:42 is great for mileage unloaded.

When I use my truck for transportation while the 5th wheel is parked at a destination is the time I would appreciate a SRW with a 3:42 gear set.

GCWR is a number 5er towers will never achieve and stay within their rear axle ratings. Those numbers are usually only achieved by towing a GN trailer.

Rear axle weight rating is what you need to watch out for.

On my 2500, I would exceed my rear GN or 5er pin weight before hitting GCWR. I can pull more (legally) with a bumper pull than with either 5er or GN. I can put 2300 lbs and change over the rear axle. But I can pull 16,300 with the factory class 5 "bumper" hitch on the back. I am under the impression that I have one less leaf in my rear springs than a 3500 of the same year. Surely that is part of the reason I have lower rear axle capability. And the front suspension/steering is also less robust in a 2500 than a 3500.

Very happy with my 3.73s
