    Just completed a 700+ round trip ATL > Gulf Shores AL > Navarre FL > ATL towing a Winnebago 21ft camper with a total weight of @ 4100lbs. Towing with a 2018 Tundra Double Cab 4x4.

    I was expecting better MPG with the Tundra compared to the Tacoma we used to tow with. I averaged about 7.8mpg on the interstate averaging 75mph. This is marginally better than the Tacoma, which was about 6mpg. There aren't any long steep grades on this drive (I-85 to 65 to 10 and back to 65 then 85)

    Didn't appear to be struggling at all with the camper, only broke 4k RPM a few times when passing uphill. At @75mph the RPM would settle at @ 2300. Only getting @ 160 miles on 3/4 of a tank.

    I was in tow/haul mode the entire time. I expect air flow drag because we're towing a blocky rectangle but I would expect better MPG given the weight of the trailer and the power of the 5.7 V8.

    What do you guys get towing with your Tundras?

    Same. You're trip and description all sound accurate.

    28ft tow behind. 8k loaded with gear and ready to roll.

    I did 800 miles rountrip to pick up a Bobcat that I purchased in my ‘18 CM with 3000 miles on it.

    The first half, with just the empty utility trailer at 2200#’s, got 12 mpg.

    After adding a 4000# Bobcat it dropped to 10mpg.

    I drove 65 mph the entire trip and suspect that doing 75 may have been the reason yours was so low. You’re pushing a lot more air at that speed.

    Slow down, even 5 mph and this will help significantly.

    Here is a trip we had horrible wind, pushed the truck hard due to time restraints. FD802922-2232-4E24-BD51-8C2D9BEF1D11.jpg

    This trip, was harder pulling but slower speeds:

    Same camper and truck.

    Sounds about right. Like the others have said. I’d slow to about 60-65 while towing a block like that. You should come up to about 9 to 11ish mpg. Also drain your black/gray/potable tanks. There is also a fiberglass deflector you can put on the front of the trailer that may help if you have the squared front end. Every little bit helps.

    I concur on the speed, the truck and I are happy at 68. I'm almost twice the weight and a little longer than you, but still around 8mpg.

    I tow a 25 ft travel trailer about 5600lbs. I average around 10 to 11 mpg towing in between 60 and 65.

    Dependa on what I am towing. I got 11 mpg towing wood and fence posts for a friend trailer and load was 4k in weight and speed was 70 mph from one expressway. I towed a Dodge Dakota for a friend that had a bad engine pushing 7k in total weight with trailer and got 9 mpg that had more stop lights and town driving than expressway driving though. Towing my Jeep Cherokee I get 10-10.5 mostly highway at the speed limit of 65-70.
