I just bought a 2017 Ram sport crew cab with the hemi. My truck has the optional 32 Gal. tank and it was $405. I don't understand why anyone wouldn't want the larger tank but most of the trucks you see on dealers lots have the 26 Gal. tank. Do some people look and say I want the smaller tank? I would like to see on this forum what tank your truck has?

Wow, $405......................

The 32 gallon tank on my 2011 Big Horn Crew Cab was $75.

Maybe that's because it is the "Big Horn" package.............

And yes, I would prefer the 32 gallon tank. Can't say why. :4-dontknow:

If I understand correctly, I can carry 26 gallons for free but to increase the capacity 6 gallons it costs me an additional $405.

When I travel I need to stop long before I need gas so I'm stopping anyway.

I'm not sure what I've gained for my $405. In fact I could have purchased about 200 gallons of gasoline or about 4000 miles of free driving.

I'm in Houston, I filled up my truck with gas before Hurricane Harvey, I was glad my truck has the 32gal tank

My Heart Goes Out....................

to the folks in that area.

I think I will stop bitching about our ND winters, as it's a cake walk compared to other places.

I'm about 1.5 miles from the Missouri River and had a scare in the spring of 2011 but got lucky. Some folks didn't.............:smiledown:

Agreed, we get the seriously cold winters, the wind is always blowing, and you might have some flood danger if you live close to a river in the spring, but otherwise, we here in North Dakota have it good....

North Dakota - -40F helps keep out the Riff Raff......:gy::gy:

My truck was on the lot too, just got lucky it had the 32 gal but like you it wasn't a "must have" item like the 3.92 and LSD was.

I can go over 400 miles on a full tank if not towing anything. The only thing I tow is an old boat so I doubt I'll be taking that very far. When I go on a road trip I plan out my fuel stops. If I see that I won't be able to make it from one stop to the next I'll carry extra fuel containers. If I was going to drive to Alaska I'd be taking extra fuel containers anyway. Obviously it's less convenient but a guy can buy a lot of fuel containers for what they're charging for the extra six gallons. :gy:

When i still had my 2009 Ram 1500, it came with the 32 gallon tank
In my business, the truckers that i escort don't like to stop except to relieve themselves & they travel 500 - 700 miles a day.
I carried 3 gas jugs that held 6 gallons each & i also had a 30 gallon auxiliary tank, that is 82 gallons total & only 78 gallons was usable.
I usually got 15.4 MPG with that 5.7L w/ 3.55 differential

Now that i have the 2016 Ram Ecodiesel, i get about 26 MPG Highway with the smaller tank, that gets me close to 600 miles per tank

The only thing that i don't care for is that too many truck stops have started selling biodiesel, instead of Diesel #2
That means that the fuel filter may not last as long

Monkey Wrench time: My 2017 2500 Power Wagon has a 31 gallon tank. Yes, 31 gallons.

I remember on my 2013 Sport the 32 gallon tank could have been a factory extra at $85. You could also have the dealer swap out the 26 gallon tank to the 32 gallon for a mere $895. Not sure how many people did this.

Only the Longhorn and Outdoorsman come standard with the 32 gallon tank. I would have ordered it anyway if mine didn't already come with it. I like being able to fill up at home where the gas is cheap and haul my trailer to the mountains and back home on a single tank of gas. My '97 Explorer only had a 17 gallon tank and got about the same MPG as my Ram gets when towing so I always had to stop at my destination to fill up again at a much higher price. Same thing when I drive to California. Once you get within 20 miles of the border gas starts getting outrageous. Once you cross the border it goes up $1.00-$1.50 per gallon higher than home. I'll fill up usually in Quartzsite and drive all over California on my tank and then fill back up in Quartzsite on my way home.

Just got my 32 gal truck last week so still getting used to it. The range said 70mi, and it took 25 gallons to fill up, which then showed me a range of 399. with a big storm coming I topped off today as the range said 250 mile, and the gauge showed 50%, the top off was 12.5 gallons. So my 2017 is not reading accurate either. I'll have a few years to put more tanks through it but it would be nice if the STAR case gets sorted out.
my 2017 is out of warranty already, anyone know if the STAR case would still be covered, or is that wishful thinking??

Are you expecting to put 32 gallon in it? If so, that isn't how they work. 32 gallon is the capacity including the dead air space.
Yours doesn't seem to be that far off if much at all. They aren't overly precise.
Also you can't go by the range and expect it to be gospel. Say it reads 5 mile range, you might go 0, you might go 20 - a lot of variables are involved.

Nah, more so sharing my experience with a new and unfamiliar truck and I'm new to the FCA family anyhow maybe its just how it is. So of the past vehicles I've owned (for discussions sake) if the stated capacity was 20 gallons and I ran it uncomfortably low with DTE saying 10 miles, I could expect to fill the tank with 18 gallons. Not that I run my tanks that low typically, that seems foolish to me, but you know it happens sometimes especially *when your lousy brother in law borrows it for the weekend while your away and leaves it on fumes. So in those situations it seems that a 10% cushion is built in or there is some margin of error in the gauging system. Whether the vehicle actually had a 16, 21, or a 36 gallon tank as in my last F series- the approx 10% seemed to me to be a recurring trend for gauge accuracy ("So my 2017 is not reading accurate either") based solely upon my experiences.

So while you say mine is 'not that far off'-and I cant disagree that its probably not that far off, it;s farther off than what I'm used to, hence the post, and since I read up on this before buying the truck its enough of an issue that I'm not alone. I agree about the variables and the biggest of those may be about what your 'used to' I guess, and I will get used to this truck. Lastly since you bring up an interesting point I wonder how much 'dead space' is built in to the tank for volumetric expansion aside from the fill tube and vent.

*The exception to my experience being a BMW sedan that was dead on the mark when at 2 miles DTE it stalled on bridge only 2,000 feet away from the pump....thanks again lousy brother in law. My 2 fuel station stops are showing closer to 20% for the Ram.
