7.5 miles per gallon? You need a truck like Airstreamer "I like not having to stop at a diesel station but once every four or five days while traveling every day on the road." ;)
Yep, here's how I worked my arithmetic:
The factory tanks carry 37 gallons of diesel, of which I can use about 30 before the gauge shows empty.
The auxiliary RDS tank carries 91 gallons of diesel, of which I can use about 85.
So, 30 + 85 = 115 gallons of readily obtainable diesel on board. I could squeeze out more, but why bother?
Towing, my 7.3L Ford pulling my 27-foot Jayco averages 14mpg.
Traveling leisurely as is my wont, I average about 300 miles per day with my trailer, or about seven hours' duration per day.
So, 300 miles per day divided by my 115 gallons stash @ 14mpg gives me 5.3 days' duration before I have to refill.
So, every four or five days, I refuel. Unless, of course, I find an area with really good diesel prices, where I would refuel a bit earlier than needed.
It's good to have options, and that's what the auxiliary tank gives me. It also allows me to significantly avoid one of my least-enjoyed aspects of towing a 47-foot rig, finding a place to refuel. Of course, most times I refuel when disattached while out dining for the night, which reduces the chore quite a bit too.
