That’s the one I have. Saved us a lot of money this past summer on a 4500 mile trip pulling a 7k TT. Was able to avoid the high dollar fuel prices in the tourist towns. It’s nice to be able to pick where and when you want to buy fuel.I've had a RDS 60 gallon aux tank in the bed of my 2500 for over 5 years with ZERO issues, used their gravity feed kit to connect it.
Has paid for itself in fuel cost savings many times over.

Not to start an argument, and I know a lot of people do it and some tank manufacturers allow for it, but gravity feeding from an aux tank is illegal... From one tank manufacturer's website:
Gravity Feeding is Illegal
Here are some laws (regulations) which pertain to gravity feed fuel tanks, and why they are illegal.
- 49 CFR CH.III (393.65) 6d; Gravity or siphon feeding is prohibited.
- 49 CFR CH.III (393.67) 7.4.5.; Fuel withdrawal fittings. The fittings through which fuel is withdrawn from a tank must be located above the normal level of fuel in the tank when the tank is full.
- In other words, the fuel must come from the top of the tank and not from a fitting on the bottom. For safety reasons, all aluminum tanks manufactured by ATTA will have no fittings on the bottom. When in doubt, look at your factory tank.
