Another question I thought of, if one uses a replacement tank or an in-bed auxiliary tank (found some good ones from Delta - but still haven't resolved the toolbox issue). How does the DIC cope with the added fuel capacity? Can it be reprogrammed, or does it become unreliable? I am leaning towards a Delta 60 gallon wedge tank and may have to forgo the toolbox. That would give me 94 gallons on-board or about a 1000 mile range. Looks like this alternative can be had for less than $800. 2600 gallons needed for break even before savings of 30 cents a gallon can be realized. Truck has 40,000 miles on it, 2600 gallons calculates to about 30,000 miles so it looks like it would pay for itself!
