I don't like my fuel tank/tool box. It works fine but it is so darn heavy. If I would do it again I would replace the factory tank with a bigger one.

 

For those of you with a long bed and or a Mega Cab you get a replacement tank from Supertanks http://www.titanfueltanks.com/default.htm. Had they gotten off their butts and made one for those of us with the shortbed I would own one of theirs so I could still have the bed room.
I don't regret it because going 800miles between fillups while towing is GREAT

 

I have a 75 gallon replacement tank. I have had for almost 2 years now and have no complaints. I still get to use all of my bed space!

Where is your spare tire???

 

2000 miles running lite and 1200 miles towing between fuel stops.

This is my first aux tank and I don't think I would have another truck without
it. I use to run from Melbourne Fl to Midway, Fl towing and without fail have 2gallons left in the tank.

Its nice to be able to just run bye that Fly J in MIdway and catch some fuel at the Fly J in Orange Texas and still have 300 miles in the system.

It all depends on what your want. I like the auto transfer system, but the gravity feed is just as effective. My system allows the trucks tank to reach
15 gallons before it starts to transfer. It will bring it up 21 gallons and stops. It continues as you drive. The controller tells you when its transfering and reads out truck tank, aux tank and total of both. The fuel gauge is set up to read both tanks as one.

they will pay for themselves & I love having mine... i never have to fill up in states that have high fuel taxes

 

Its there. It hangs maybe 3in lower then the factory position. You really cant tell.

 

When I was at their shop. Their dodge Ram also and little tanks mount on the inside of the bed behind the wheel wells on each side. I can't remember how many more gallons it added.

 

Regardless of the type of tank the extra fuel is very nice to have, I can go to the mountains and tool around and come back home without having to worry about how much fuel I use while I"m at 10,000 feet and 40-50 miles from the closest station. My factory tank leaked out the breathers with a gravity feed, I added a solenoid valve to shut my aux off when the main tank gets full, works great.

 

I also have the Aero replacement tank in my '02 (Aero is in Corona, CA) and had it installed when truck was almost new. It holds 64 gallons and you can't see it. Completely hidden. Fuel gauge works as on the stock tank. I wouldn't be without it - but there are a couple of things..........

1. It's pretty expensive - I understand they're over $1,000 installed now.
2. The attitude of the people running the place and doing the work is really offensive. They may have changed since '02, but I wouldn't hold my breath. I spoke with a lady there on the phone last summer about a problem and came very close to telling her to ****off.....and I am ALWAYS courteous on phone.
3. Problem I called about was having to replace missing bolts twice in 150,000 miles and now was missing 3 more. That scares me. The thought of a full 64 gal tank coming loose on the freeway..............???
4. Excellent truck shop (Clarke's) in Santa Fe, NM pulled the tank to repair a hairline crack last summer and found that it was mounted solid to frame, several bolts wre missing and 2 mounting tabs were broken off. It "apparently" can't take the flexing of frame with a camper on board. The lady at Aero was Very snotty when I called her for an opinion and a price on a new tank. Ernie at Clarke's welded them back on and re-inforced them, then re-mounted the tank on heavy rubber pads to allow some flex and still be very solid and secure.

I wouldn't be without the extra capacity and really like the hidden tank, but would look for an alternative to Aero.

Years ago, I had two fuel tanks from Dodge Ramchargers in the bed with electric fuel pumps switched to transfer fuel. They were side by side in the front of the bed with a home made tool box over them. I lost about 3 foot of bed length but if you get the plastic tanks used in the 1974-86 or so RamChargers and Trailduster, you get 36 gallon each. That will give you 72 extra gallons of capacity. I was running out west and fuel stations were sometimes few and far between. Plus, the more remote places reeeaaallllyyy like to charge for their fuel. I had extra fuel gauges under the dash so I knew what was in each of them. The metal tanks in those trucks are only 24 gallons.

 

For a $1000+ I will simply stop more often or carry 5 gallon cans. I had been thinking of a larger tank or in bed tank but not anymore. 5 gallon cans work just fine for this poor boy.

 

I've got a 37 gallon fuel tank/toolbox made by Deezee. Have it set up with a manual ball valve gravity feeding to the main tank. It has a 12 volt solenoid shutoff inline. I also carry a 3/8"nipple in the toolbox, just in case the solenoid fails. 2 hose clamps and I can bypass the electric valve.

After about running out of fuel at 3AM in the middle of nowhere SD, I bought it on the way home. I'll always have one in my truck from now on. Lots more peace of mind, fill up when I want to, and save a little money here and there with cheaper fuel. I also live 35 miles from the nearest fuel station. Drive around out here for awhile and I'd have to go to town, just for fuel since the only bulk tank I have out here is dyed diesel.

Kind of long, but short answer: yes, I think they're worth the money.

 

I would like to thank eveyone for the input.
I would say " if you do this to save money it just isn't going to pay for itself"
The big plus looks to be the added peace of mind on long hauls with a secondary advantage of choosing to fuel up rather than having to fuel and perhaps being luckey enough to save a few cents.
I must say I am now kind of torn between the replacement tank and the tool box/tank combo going into the bed. For certain it has to be below the bed rail so the 5er is not impacted and I like the idea of the bed cover when not towing.
Please feel free to add additional coments I think we all save money when we share experence.
Oh almost forgot. Pulling doubles you do have to watch where you can and can't go but that has not been too big of an issue. As for backing up it does take some time but I have done it a number of times when I did not have a way out or got parked in. It has happened driving over the road with the Pete too.
Thanks

 

i made my own tank out of aluminum,50 gallon gravity transfer with an electric pump to help the transfer...about 1200 mile cruising range
