The Urea tank on the Dodges have left me a little wanting since they're only 5.5 gallons in total.
Curious, how big would you like DEF tank to be? The tank on my Freightliner daycab is 13 gal and an OTR tractor is around 20 gallons. Seems the 5.5 gal on a pickup is ample.
My daycab burns about 415 gal of fuel a week and use about 13-14 gal of DEF a week or 3.13%. Average run less than 100 miles on 2 lane so mpg suffers.
8 to 10 gallons like what the Grand Cherokees and RAM 1500's get (and they use fuel at a much slower rate). Average shelf life of DEF in the US is 1 year, so for the lower use vehicles that would work just fine. For the higher use vehicles, 8 - 10 gallons would make the DEF last about as long as an oil change in unloaded circumstances for most people (those that travel more or less about 15,000 miles a year).
