I'm watching this thread. My new Ram has 32 gallon tank, which I get about 250 mile range with the 6.4, however, looking at a trip maybe this spring that has a 300 mile stretch with no services.
Looked around at TSC, even the small transfer tanks are expensive, and have warnings about diesel fuel only, no gasoline. I guess there must be a lot of certifications, or insurance on these tanks to make them so expensive?
I have two 5gal Eagle safety cans, they're short and fat... I might build some sort of rack for them to sit in, and buy two more so I can carry them 2x2 so to speak.
