On the road, time is money. Regular stops to refule can take their toll on your workday or extend your drive time on road trips with your 5th wheel trailer. Dee Zee Combo Auxiliary Transfer Tanks are tested and certified to hold diesel fuel for refueling equipment at the job site or for transferring directly to your truck's fuel tank during longer commutes and storing tools of your trade.

Our tanks are constructed out of non-rusting 0.125 Brite-Tread aluminum with radius curve design to eliminate key weld pressure points and are hydrostatically pressure tested up to 29 psi to ensure they meet the highest level of quality.

Extra fuel when you need it, siphoned directly to your gas tank. Go ahead, skip that next exit with confidence. Our sophisticated connector kit (sold separately) allows you to move fuel directly from your transfer tank to your fuel tank. Auxiliary Fuel tanks meet Federal DOT and Federal Motor Carrier Safety Administration requirements for tanks to perform as an Auxiliary Fuel system.

See what our Experts say about this DeeZee Truck Tool Box

  • Why Can't DeeZee Auxiliary Tanks Be Used for Gasoline
    Auxiliary fuel tanks like the DeeZee Combo Tank # DZ92740X that you referenced should only be used to transport diesel. We have reached out to DeeZee in the past regarding this and they said that this is simply because gasoline is much more explosive than diesel fuel so the potential danger and liability is much greater. Technically the tank would hold gasoline just the same as diesel but it's not something that DeeZee recommends and it would void the product's warranty.

  • Is DeeZee Combo Auxiliary Tank # DZ92740X Approved For Commercial Use
    The DeeZee Combo Auxiliary Tank # DZ92740X meets the Federal Department Of Transportation requirements for UN31A and UN31B tanks and meets the Federal Motor carrier Safety Administration Requirements for diesel auxiliary tanks. I did some research online and found that there are several requirements to get the UN31A or UN31B certification. You may want to check with the Department Of Transportation to see if these certifications are good for commercial hauling.

  • Can Transfer Pump be Used with DeeZee Transfer Tank # DZ92740X
    Yes, transfer pumps can be installed on the Deezee part # DZ92740X as long as it's a center mounted transfer pump.

  • Will The DeeZee Combo Auxiliary Tank # DZ92740X Fit In A GMC 2500 Short Bed With A 5th Wheel Hitch
    The DeeZee Combo Auxiliary Tank - Brite-Tread # DZ92740X is a confirmed fit for 2014-2019 GMC 2500's with a 6.5' or 8' bed and is 54" long x 18" deep x 17-3/4" tall. I recommend placing your 5th wheel hitch in the bed of your truck and measuring from the cab side of your hitch to the cab of your truck to ensure you have enough clearance for this 18" deep toolbox/tank and that it won't interfere with the handle motion of your fifth wheel.

  • How To Add a Fuel Tank To a Truck with 5th Wheel Hitch In Bed
    Yes, the best option we can offer you to add fuel capacity is with the DeeZee Truck Bed Auxiliary Tank part # DZ91752X which should fit in the space you have between the cab and 5th wheel hitch no problem as it is only 9" deep. I don't have any specific measurements on different hitch/truck combos but the above will work for most on the market today. The DeeZee Truck Bed Auxiliary Tank will provide up to an additional 38 gallons of extra fuel. The DeeZee Combo Auxiliary Tank part # DZ92740X...

  • DeeZee Combo Auxiliary Tank for 2017 Ram 2500 w/ Rambox
    I have a solution for you but the DeeZee Combo Auxiliary Tank item # DZ92740X you were looking at will not fit between the Rambox's on your 2017 Ram 2500. It is 54" long not 47" like our website says. It's being updated. You will need the DeeZee Combo Auxiliary Tank - Brite-Tread item # DZ91741X. It measures 48" in length, by 30" in width, by 24".

  • Auxiliary Diesel Tank and Toolbox for 2015 Ram 3500 with No Bed and 5th Wheel Hitch
    We do have combo transfer tank/tool box # DZ92740X from Dee Zee which holds 43-gallons of diesel fuel and that measures 54" long x 18" deep x 17-3/4" tall. Since your truck does not have a bed you will probably need to have some fabrication done to provide mounting points. I cannot tell from your photo what space is available right behind the cab for mounting a tank so you'll want to compare this to the tank/tool box dimensions. You'll also need Connector Kit # DZ97962 (made for you Ram...

  • Dimensions for DeeZee Tank/Toolbox Combo on 2016 Ford F-250 Short Bed
    The DeeZee Combo Auxiliary Tank # DZ92740X referenced in your question is actually not confirmed to fit your 2016 Ford F-250 short bed. The tank and tool box measures 54 inches long, 18 inches wide, and 17-3/4 inches tall. For your particular truck, I instead recommend looking at the DeeZee Specialty Series Transfer Tank/Toolbox Combo # DZ92647, which is confirmed to fit. This tank/toolbox has an aluminum construction and has overall dimensions of 46-3/4 inches long, 32-3/4 inches wide...

  • Why Does Valve for the DeeZee Connector Kit 97962 Have to be Closed During Travel on 2019 Ram 2500
    The Connector Kit for DeeZee Truck Bed Auxiliary Tank part # DZ97962 must remain in the off position (valve closed) during travel because the extra volume via the lines and auxiliary tank could introduce an emissions error into the system which could then cause a check engine light to appear which may or may not place the vehicle into limp mode. If you have ever gotten a check engine light from not tightening the gas cap this would be the same type of emissions error as the above. Please...

  • Is Truck Bed of 2018 Ram 3500 Secured with Extang FullTilt SL Tonneau Cover # EX38435 Installed
    The Extang FullTilt SL Soft Tonneau Cover # EX38435 referenced in your question, which is confirmed to fit your 2018 Ram 3500 as long as you have the 8 foot bed, features locking levers that secure the bed when the tailgate is closed and locked. The hatch-style cover cannot be lifted without accessing the lever near the tailgate. This simply means that the cover can't be opened unless the tailgate is open so when the tailgate is closed and locked your bed will be completely secure. I...

  • Will The B&W Companion # BWRVK3370 Fit A 2013 Ford F-250 6-3/4' Bed With A 75Gal Tank/Toolbox
    Due to the size of your fuel tank and the shorter bed length you would not be able to fit your tank/toolbox and the B&W Companion OEM 5th Wheel Trailer Hitch w Slider for Ford Towing Prep Package - Dual Jaw - 20K # BWRVK3370. This hitch is only going to give you approximately 22" from the front of the bed to the closest part of the hitch. To be able to install the # BWRVK3370 you could use a smaller tank/toolbox like the DeeZee Combo Auxiliary Tank - Brite-Tread # DZ92740X.

  • Transfer Tank and Toolbox Combo for a 2013 Chevy Silverado 2500 Short Bed with Gooseneck Hitch
    We have a couple of transfer tank/toolbox combos you could use in your 2013 Chevy Silverado 2500 short bed. Both are 18 inches front to back, # DZ92740X and # DZ91740S. Using that 18 inch measurement you can determine if there is space enough or if the tank/box would be too close for the coupler to fit or turn. The body of the trailer should not be an issue.

  • Compatibility of a Combo Auxiliary Tank and Tool Box for a 2017 Ram 3500 with B&W 5th Wheel
    Before you can decide on a tank/tool box combo for the bed of your 2017 Ram 3500 truck, you will need to measure the distance between the 5th wheel hitch and the front part of the bed. The measurement should be from the front edge of the front pucks to the front edge of the bed. This distance will give you an idea of how much room you will have to install an auxiliary tank and tool box combo. DeeZee has 2 tank and tool box combination that might work for your application.

    If you want a single item that can both store tools and supply additional fuel capacity for your Ram 3500 long bed you might consider the DeeZee Combo Auxiliary Tank # DZ92740X. This unit combines a 43-gallon tank and a tool chest in one product that measures 54 long x 18 deep x 17-3/4-inches tall.
