Miles per gal ??

Sorry if this has been ask before, but I'm new on this site. So I would like to know what kind of real world towing a 5th wheel with weight of 10000 to13000 lbs mpg I may get with a 2020/2021 F-350 ccsb sw 4x4 diesel ? Just doing my homework and making sure I'm doing the right thing. BTW, the unit we are looking at is 30 feet long, and 12 feet high, weight is around 10,000 lb.

Thanks

Average is about 11MPG plus or minus your driving habits.

I talked to a guy with a 13.5k 5th wheel, and he gets 11 mpg with a '20.

I got right at 10 mpg in my 2020 450 pulling a 40’ 5thwheel weighing around 23,000 . This was driving 60-65 in 95+ degree temps.

Mines a bit older, 2015 6.7 SRW CC with an SCT tune set for towing. My 5W is 35ft 13,000lbs, and I get 12.2 consistent, head wind will drop to 10.

I get around 10-11 locally with mine.

Last summer with a 6K trip I averaged 9.1 down to Florida and then to Arizona Colorado and back.

Mine is a high profile.

I have the same truck in a 2017 model year. 3.55 gears.

Calculated (not the dash reading), I get an average of 10.7 mpg pulling a Grand Design Reflection 337RLS driving conservatively. Loaded for camping the camper is over 12,000 lbs. 68 mph on the interstates seems to be the sweet spot for my setup. Sometimes I get upper 9s, a few times I have gotten mid 12s. Headwinds, tailwinds, traffic, hills, speed, regens, campground setup, and fuel are all variables. Using a spreadsheet, it all averages out to 10.7 mpg with the times I have filled up with doing nothing but towing.

Note: I recalculated my mileage, and it comes out to a 10.7 mpg instead of the 11.0 mpg I originally posted.

I've found mpg to be noticeably affected by percent of soy diesel. I hover around 11.5 mpg running our 5 ton fiver at 70 mph. Drops as low as 8 mpg with high percent of soy.

With my set up below, with a trailer weight of around 16k, on the highway at 65-70, I always get 10-11 mpg according to the truck.

Best advice and the one I have always followed, was to project 8mpgs in the budget and Fuel prices at $3.50 per gallon.

I also caculate an average of 50 mph in figuring how far I will travel in a day.

Good average to use if you are figuring a cross country run and when you will arrive at your destination.
