Additional or Larger Fuel Tank.

I'm curious what you all think about larger fuel tanks or additional tanks? I'm not sure how needed they are. Sometimes I think having a standard tank forces you to stop and take a break. With that said so far I've only taken trips where fuel is always readily available.

They are not cheap. When fuel was high they would let you take advantage of the best prices. You can buy a lot of fuel for what they cost even more if you pay to install. They may make sense for western travel. You need to stop anyway so you can plan stops around your fuel needs.
Personally I would not opt for it. Let's just hope fuel prices stay reasonable.

I had aux. or larger tanks in my last three trucks. But then factory tanks were just 25 gal. which is inadequate for a tow vehicle. Present truck has 36 gallons and it is OK, but on long trips I really have to pay attention to fuel stops. I much preferred having the larger tanks, then I could take rest breaks when and where I desired, not when the tank was getting low. But it is kind of hard to justify the cost and effort for a larger tank for just an extra 12 - 15 gallons, which is all I would want.

I don't try to justify a larger tank based on fuel savings, but rather on convenience. But fuel savings is an extra benefit, and it is real regardless of current market prices, especially if at the end of the day you can seek out fuel stations off the beaten path.

I have a range of about 400 miles when I'm towing with the standard fuel tank on my truck. I don't need to go any further without refueling. Auxiliary tanks would just take away from my payload.

I had a std 26 gal tank and it was TOO SMALL for towing my 5er. I have had Transfer Flow tanks installed in my last two trucks and love the added convenience of stopping when and where I want or not stopping at all for gas for the entire day. Yes they are expensive but I had a few extra bucks and really hated stopping every 200 miles (sooner if the DW was watching for the gas light to come on!). And it always seemed to be in the mountains or somewhere where gas was more expensive. I don't regret it at all.

I installed the first tank myself and it wasn't too bad. Hardest part was lifting it up on a floor jack into position.

I have the Titan 51 gallon in my F250. It is awesome to not have to stop as often. The stock tank was just too small.

Just ordered a truck and ordered the 36 gal tank. That way I can get a little further before the wife panics because the gas gauge is below a 1/4. Or worse, the gas light comes on!

I think the larger tank ran me about $180 more.

I too thought about it long and hard given that we get about 9 or so with my load and driving 'style' and only have a 26 gallon tank...

But for a few reasons in order of importance:
1) wife's bladder and hawk eyes on fuel guage
2) payload
3) I trade trucks too often
4) there are truck stops at least every 200 miles and we have the apps to tell us..

just never bothered...

I installed a Titan 50 gallon stock replacement 2 years ago. I can tow about 550 miles without fueling. When not towing my range is about 900 miles. It allows me to choose when and where I fuel up (more important with a diesel). A normal day of towing and I can refuel after unhooking the 5er. I don't save any money by it. I just like the convenience. It's a $1,200 upgrade. I installed it myself. I make regular stops for a break but they are usually at a point of interest and not a fuel station. I would never go back to a 26 gallon stock tank that is standard with a short box truck.

I just checked out the 50 gallon Titan for my 2015 F-250 SD. It was a bit of sticker shock. Prices ranged from $1,200 to about $1,600. I'm not quite ready to take the leap to a larger tank since we are not yet full time RV'rs. Thanks for the post. I'll keep the tank conversion in mind when we move to full-time, on-the-road status.
