06 chevy aux fuel tank

Peggy bought me a Farm Store tank, and a electric transfer pump and handle from Craigslist. Less than $300 for both. I do have to get out and manually put the fuel filler in the truck tank opening and turn the pump on, but not that big of a deal.

It's only a 40 gallon tank but allows me to pick and choose where I want to stop for a break. I also no longer have to make sure I can get into and out of a fuel station with that 40 foot toy hauler. :) I fill up at the end of the day when we're unhooked. I wouldn't be without one.

I installed a 91-gallon RDS aluminum tank from Northern Tools a few years ago and love it. I use it not only for refueling the truck on really long trips, but also for refueling a tractor, generator and RTV on the ranch. To get all this done, I installed a 13 gallon-per-minute fuel pump along with filters for extra protection.

It's proven to be a valuable asset to me.

have been think about getting a aux fuel tank for my 06 chevy duramax. replacement titan tank for under the truck seems a little pricy. looked at some from northern tool. anyone got any ideas?

Titan and Transfer FLow are the only two tanks I'd consider.

I'm not a fan of in bed tanks because they take up my bed space, and create extra wiring and plumbing, and holes in the truck bed if you want to transfer from the aux tank to the main tank while traveling.

I may someday do a Titan replacement tank when I start traveling more.

So apologies to b-dog for highjacking this thread. I have an '02 Silverado dually long bed and am looking at in-bed auxiliary tanks. Pretty much had decided on the RDS 51 gal. fuel/toolbox, or the 60 gal. fuel/toolbox combo. Both are 19" tall according to specs. I measure 19-1/2" to top of side rails. Really want the toolbox option. Have been looking at hard tonneau covers but am undecided as the fuel tank needs to sit 1-1/2" from front bed rail to allow toolbox to open, and don't seem to see any covers that will work and still allow opening of toolbox. Also have fiver hitch in bed. Anybody have recommendations? Thx.

We have a 2015 CCSB and Access Vanish tonneau cover. We initially purchased the 60 gallon thinking we could make it work, but it couldn't be moved over enough not to interfere with the tonneau rails while leaving enough room for the valve and tubing on the other side. The 51 gallon model works fine. The lid doesn't open completely because of the tonneau rolled over it, but it does open sufficiently to get anything in and out of it that we store there. The storage is really quite minimal, being only 6" deep. Still, we use it for a socket set, a spare gallon of DEF, and some other fluids we don't need to access very often.

LOL! Yep, I have to pee quite often because I'm always sipping a Coke Zero or something. But we stop where we want to stop: rest stops, restaurants, or truck stops.

The auxiliary tank will never pay for itself. Its just something I like having. Our trip to Disney two weeks ago, the tank wasn't even full when we left home and we still didn't have to get fuel until we were almost to Daytona. Then we didn't have to get fuel at all coming home. Fla to NC. Its more of a convenience thing, I guess.

Don't y'all ever have to pee, or stretch your legs? I've got a range of about 200 miles which is 3-4 hours. After that long in the seat I'm ready to walk around a bit.

I'm in Georgia so I'm never far from fuel, I know out west it can a long way between fuel stations.

I got the 91 gallon RDS fuel tank/tool box combo from Northern Tool. It is gravity fed and works like a charm. Towing my condo around the country, I have a range of over 1,000 miles between fill-ups. It does take up most all of the bed in front of my 5th wheel hitch but I don't carry anything in the bed anyways. It was an easy install.

I have the same tank. Its the second truck I've had an RDS from Northern in. Tool box on top. Love them.

Gravity flow keeps up with demand just fine. Pulling the camper at 72mph, I'm getting around 9 mpg. If I'm thinking this correctly, that means I'm burning though 8 gallons of diesel every hour. Or a gallon every 7.5 minutes. The truck's gauge never drops until the tank runs out.

RDS was offering two models of the 91 gallon tank. One is level to the top of a typical truck bed but extends further into the bed. The other sticks up about 3" above bed height but doesn't take up nearly as much bed space. I have the second one.

I got other things i would rather drop bucks on.

I bought an RDS tank from nationwide wholesalers. It was made in Perry FL to my specs and shipped direct from Perry to my door for less than I could have gotten it from RDS. Go figure. Great folks to work with at nationwide 4 years ago.

i plumbed in myself just about the same as described above.

i "heard" that RDS manufactures the tanks that northern tool markets.
