I am looking to get a bigger tank for my 2011 1500 I have done mods to the engine and get 11mpg on average I like the power but id like to go longer than 5-7 days to fill it up and more than a 250mi range. (I only have 24 gallons currently) any help is much appreciated, thanks

 

Only thing I can think of is shoehorning a 35 gallon gas tank off a long-bed Chevy. Thing is even if you could mount it, will all your fuel hoses, vape tubes and wires reach the larger fuel tank? You'd likely have to have all of those too, to make this idea work.

 

There are a number of after market options. Have seen oversized tanks that replace the o/e or bed mounted.

 

alright thank you guys
