Reduced Capacity & Range?

[Mack]

I have a deposit on OverTrail+ to replace Jeep GC EcoDiesel and towing a travel trailer just doesn't seem practical. Towing in the mountains will result in 10 mpg or 200 mile range pushing it. Talk about range anxiety.

I too switched from an ecodiesel overland. I miss the 30mpg on the highway!

Seems like a pretty average per tank distance.

But you'll probably only get 50-70% of that when towing. That's why the 28-32 gallon tanks on the Expedition Max/Suburban/Yukon XL and the 36 gallon gas tank on the F150 are clutch.

I have a 2024 Luxury +. I was on the list in Feb 2024 and got it in December. I traded in a 2015 Nissan Armada. The Nissan had a 28 gallon take. The new 2025 Armada has a 23 gallon (I looked because I was going to sell my Lexus). Anyway, no matter what I do, when I fill up the tank? I never get a distance to empty at 300 or higher. Usually around 288. This has been the most disappointing aspect of this. I after market isn’t an option because of warranty issues. I understand the so called reasons for making is small, but I don’t care about a battery for another version, and citing the sticker shock filling it up, then folks should not have bought a SUV. But. Oh well. Other than that, and limited functional storage between the driver and passenger seat it’s a great ride

Does the addition of an auxiliary tank void a warranty? The tanks like those from LRA use the existing vapor recovery and nothing connects to the control computer - not sure why that would impact the NVW -

I was speaking about replacing the existing tank with an aftermarket larger tank. That will indeed void the warranty. I wasn’t thinking of an auxiliary tank

I’m leaning toward the 14g aux tank - that buys ~35g of capacity at 15mpg to 525 miles of range

I'm a serious hypermiler and commute 120 miles daily on all highway, all flat and I drive the speed limit like a granny. I am looking forward to putting this to the test. I ALWAYS get 4-7 more MPG than MGF claims.... and I do overfull the tank slightly so excited to report back when I get the car.

I'm 3500 miles in - I'm driving calm since this is not a sports car - I'm averaging mid 16's in comfort mode.

Just got out of a 2025 Hyundai Santa Cruz which claims 27 highway and I regularly average 34.
