Fuel mileage pulling a camper?

Hi guys, I’m considering purchasing a 2024 Toyota Tundra SR5 with Xp package 4x4. What I’m wondering is what kind of mileage could I potentially see with pulling a 3800 lb camper? Most of my travels would be on the east coast and very little high grade roads, mostly flat driving at 65 miles an hour.
Any help in this regard would be greatly appreciated, thank you in advance!

Plan for 7-8 mpg, if you get better you will be happy.

But think about this, you and your family will be the last to use it. Nothing to worry about.

 

Ok, I talked to a guy who says he was pulling a 10,000 lbs camper at 70 mph and got 8.8 mpg. So I was hoping that by pulling a 3rd of that weight I could get at least 10 mpg wishful thinking?

 

Weight is only part of the problem. The main issue is it's a giant sail back there catching the wind.

 

It has been my experience that many people exagerate their fuel mileage.

 

Agreed.

Try holding a sheet of plywood in 60 mph winds.

 

I track my entire trip.

850 miles from the middle of Michigan to South Carolina.

I drag a half ton towable 5th wheel camper 2x/year. Let's just say it it's close to 9000 lbs. Don't want to start an argument.

My 5.7, running in 4th the entire trip gets me 9.2 mpg. I rarely see 70 mph.

My best was 9.7, but I had awesome tailwinds the entire trip.

 

My single axle Minnie Winnie was about 3,500lbs on the axle and another 700lbs on the pin. When I kept it to 60-65mph, I could get 10mpg with my V8. A light headwind quickly dropped it to 8-9. The newer engine might be a bit more efficient, but you cannot overcome physics so I wouldn't expect you to do much better.

 

I used to pull a 5k gvwr 17’ toyhauler with a Nissan frontier. Always got around 9-10 mpg. Pulled the same trailer with a 2022 Chevy traverse and got 10-11mpg. Looking at the other forums (ford, Chevy, molar, etc) everyone seems to get around 9-11mpg no matter the motor as long as it’s gas (no diesel).
I have a 3k mile trip starting next week towing a low profile 12’ 7500gvwr cargo trailer. I’ll be thrilled if I see 12ish mpg.

 

I get 9-10mpg pulling ~6500lbs of travel trailer thru the Colorado mountains (usually). Average speed of 65mph, 70 if Im tryin to keep up with the homies.

5.7l, 6 speed, 4.10 rear, 2" level, <34" KO2's

I will not complain.

 

Yerp... I be willing to bet (of course we would never do this) that you' get better mileage pulling a 15,000 lb. flatbed trailer than a 5,000 travel trailer with a large frontal area (AKA Parachute)

If I'm planning a trip I just budget for 10... It might be a little better, might be a little worse, I don't really pay that close attention 'cuz if I'm towing the trailer then I'm on vacation.
