Just setup some "on-road" fueling just like what occurs "in-air" with Naval & AirFarce aircraft when flying for further distances then what their "bubbles" aka droptanks can provide for.

Perhaps a retractable probe extending out of the truck cap with a piercing front end, see a tanker on the road and puncture the side, fuel up - then get the heck out of there just like in a Mad Max movie....

Thanks everyone for your 2 cents. Keep the ideas coming.
You may want to check J.C. Witney for larger replacement tanks for gas if you run out of options for an inbed tank. I had doubled the capacity of a van I used to have by swaping out the OEM tank to a larger aftermarket unit. When I did that I lost the extra space for the spare and had to carry that inside.
It was a cheep solution and had no computers and no way to tell how much fuel was in the tank till it was half full, then it would start to register on the OEM gauge. I used it that way for many years and never a problem.

On my present truck with diesel and an in bed tank with a cap on the bed, I have no fumes as the fumes are vented outside the truck bed. So if you do find a inbed tank that suits your need, just make sure it has a way to vent the fumes directly from the tank to the outside. Mine does it in 2 places, at the overfill at the fuel fill up and also with a tube that passes directly from the tank thru the bed to underneath of the truck.

On edit, rethinking the vent underneath the truck may not be such a good idea with gas fumes. It might be worth a question or 2 to the manufacture though.

Larger fuel tanks used to be a common mod in the 1970s but federal regulations, both DOT on fire safety and EPA on evaporative emissions, sent those the way of the dodo, especially for gasoline fueled vehicles. The prices on oversize replacement diesel tanks from Transfer Flow and Titan reflect the considerable compliance costs these companies incur.

Yes you can get in-bed refuelling tanks. They are rated for diesel only but many people put gasoline in them. I wouldn't.

Federal regulations prohibit installing any fuel tank with a gravity discharge or any sort of connection for transferring fuel to another tank on the vehicle. In practice the only two legal choices are a larger replacement tank or a refueling tank in the bed that can be used to manually refuel the main tank while stopped.

Refueling tanks pose a risk of contamination and stale fuel so you can't just fill it and leave it -- you have to rotate the fuel through it regularly even if you aren't in a situation where you really need to use it.

With the prices of these mods, the hassle, etc., it's not worth it IMO unless you're out in extremely remote areas or have a truck with unusually poor range with its factory tank.

My Suburban came with dual fuel tanks from the factory providing 38 gallons of capacity total. It's a well-engineered setup, they fill from the same location, switch automatically, and the fuel gauge shows the total.

Aux Fuel Tank

We purchased the ATI Aux Tank and have been very pleased. They have a lot of options. Locking fuel cap, fuel gauge, shutoff valve on the tank, filler neck filler with ball valve. We ask for a couple of custom changes to our tank and the company was very accommodating. The installation was very simple and we have had no leaks or other problems.

Where is your tank installed? In bed or under your tow vehicle?

My 2012 Dodge fuel gage could not be calibrated to the new tank capacity. However, the trip meter has two tracker areas and one is reset with each refueling. Since I record gallons and mileage on my iPhone (info floats over to the iPads as well), I have a good idea what the real mpg is. With 56 gallons, I figure I could get over 600 miles. That is longer than ten hours. Great range, except my bladder can not last that long. So that tends to color my range as I usually refill the truck tank when I empty mine.

What got me started on this is on this site people have complained about being able to find gas stations that can accommodate a 25' trailer. Being a newbie to RVing I of course freaked out. The truck is coming with a 36 gallon tank so perhaps that is enough and I will just have to look for truck stops for refuelling.

I think you'll find that the 36 gal is adequate or most of your travels. In my Dodge I have a 34 gal tank. Like already mentioned by that time I need a stop anyway to stretch my legs if nothing else. I've rarely had difficulty finding a station with enough room and I have a 30'er. Yes some are tight and I've had to by-pass a few too but usually I can find one without too much trouble

Read the owner's manual

Whatever brand of diesel TV is acquired, carefully read the owner's manual, specifically in the fuel area to see what percentage bio-diesel may be used without voiding the warranty. Note that Love's truck stops clearly state on their dispensing pumps for both big rigs and the car side that their fuel may contain from 5% to 15% bio-diesel.

My 2012 Dodge manual states a tolerance for up to 5% bio-diesel for the Cummins. Using a higher percentage can void the warranty for engine damage caused by a higher percentage of bio-diesel.

YMMV

switz,

I am just wondering if you had the Titian 60 gal. replacement tank installed in your 2012 Dodge? I am considering this option and was told that the new capacity could be calibrated for accurate reading of the fuel gage.

Is there something I missed, don't understand, or we talking about different models.

Also, are you aware of any warranty issues with your replacement tank?

Thanks for any info.

The largest Titan diesel tank for the 2012 Dodge diesel short bed truck in January 2013 was the 54 gallon tank. Their 60 gallon tank fits a long bed truck. Any leaks from the tank itself fall on the Titan warranty. All the mechanical and electric parts associated with the fuel pump are switched over in their entirety, so those would still be Dodge's responsibility. However, I added a Cummins water separator filter between the tank and the engine fuel filter and a two micron Cummins fuel filter between the engine fuel filter and the cp2. In less traveled areas, one can encounter less than pristine fuel.

I was told that there was no way to calibrate the fuel system for distance to empty. However, the fuel level seems close. I use a sub trip meter to check miles on the fillup and know approximately the mpg at every stop. The truck's range far exceeds my personal range between stops....

I also retrofitted both an engine oil auxiliary filter and an auxiliary transmission fluid filter. I am not extending service intervals and in fact plan to change more often. Oil has always been cheaper than main bearings replacement.

All steel springs were removed from the truck and replaced with Firestone airbags as part of the complete level ride Kelderman suspension package that also includes an air storage tank with compressor, so I have an outlet on the back of the truck to connect an air hose for trailer tire and truck tire inflation. The front stabilizer bar was replaced with a stronger unit and the steering gear box support was reinforced. Dodge would not warranty the suspension changes.

A warranty issue discussion might be interesting as Dodge attempts to weasel out of responsibility for anything except perhaps a window crank.

Thanks for your explanation. I do have a long bed. At least, the info the salesman told me is accurate concerning the calibration. Also, I had no clue about the options for the fuel and transmission filter. Who retrofitted your engine oil auxiliary filter and an auxiliary transmission fluid filter, you or Dodge?

You have made some serious changes. I did consider the "Banks" Cold Air System and the Exhaust system. When all was said and done, I decided against it. Based on the cost (parts alone about $850) for only one or two miles increase, to me, does not justified the cost.

The Curt 15409 rear receiver rated 2,550 pounds along with a Curt front receiver were installed by a local RV shop in Indianapolis the day I picked the truck up from the dealer. The Curt hitch dropped the receiver height about four inches.

While at the Kelderman factory is Oskaloosa, IA doing the level ride air suspension install, I had them cut off the factory receiver which was inadequate for my tongue weight and forums reported issues when a WD hitch at max weight was attached. By lowering the bed to level, the receiver opening required only a two inch off set for my Hensley hitch so the truck and trailer ride level. I also had them install larger differential covers front and rear for more cooling oil and heat dissipation. They installed the Insight CTS gage system on the drivers door post with a pyrometer so I can see turbocharger inlet air temperature, inches of boost, fuel rail pressure, transmission oil temperature and both differential oil temperatures. The factory dash has water temperature, engine oil pressure and alternator output.

The Titan tank folks recommended an independent shop (Salem Boys Auto in Tempe, AZ) to install their tank. Salem Boys also do serious custom work along with regular maintenance and performance upgrades. They installed the Titan tank and all the filtration modifications. (Put FS-2500 filter into google to see the engine and transmission auxiliary filtrations systems) They also installed the beefier front suspension and steering parts. Any performance improvements will also be done there. All maintenance is done there by master certified mechanics, not the two week wonder graduates from a mechanics school that can barely hang onto a screwdriver.

Once the suspension modification was completed and all the extra filtration installed, there would be an easy way out of warranty claims by Dodge on the entire driveline including the engine. So thorough regular maintenance at shorter intervals can prevent most issues.

Don't have to go back that far. I had the same funnel and hose rig in the jet fighters I flew back many years ago, called the "relief tube". There was a spring-loaded button at the base of the funnel to open it up to the low pressure outside. It was quite a feat to use the relief tube with winter flying gear, parachute straps, etc, but the autopilot helped a lot. It would be quite a feat to safely drive while using it.

By the way, I have a TransferFlow 40-gallon in the bed of my diesel. Wouldn't be without extra capacity. I can tow close to 2 days before refueling.
