Except for the commercial drivers, I am wondering if an auxiliary tank is cost effective. Diesel fuel weighs around 6. 8 pounds / gallon. Say you add 100 gallons of capacity. You will be packing over 700 extra pounds (with tank and fuel) for a good number of miles. I understand that fuel prices vary greatly, but the initial cost savings will be offset to some extent by the extra fuel burned packing the extra weight several hundred miles. You will also, of course reduce your payload capacity by the same 700 pounds in this example. Running solo, we should all be going around 600 miles with the stock tank, and that is probably going to equate to several potty or food stops anyway, so why not fuel then, instead of packing all of that extra fuel around? I can maybe see a need where you are running commercial, moving heavy loads, and using a lot of fuel. Time is money in that case, but quite frankly most of us are not in that category.
I know I will probably get some flak for taking the contrary opinion here, but I have the flame proof suit on and am waiting. I guess I just want to stir the pot a little, and see what the rational is for being able to drive up to 1000 and even 2000 miles without fueling.
