Just crunched the final year-end numbers and something interesting popped up - even though we stayed only on the west coast (Baja to Washington) we put almost 15,000 miles on the van this year which is the van's second largest annual-miles-traveled since I bought it back in 2010 (I did 17,000 miles in the 9 months I owned it in 2010). We even spent six weeks out of the van, and on the boat, which means Big Blue didn't move as much during that time.
The total cost in gasoline was just under $4,800. It is the greatest amount ever spent on fuel in a single year, by $1000, thanks in large part to spending so much time in Baja, MX and California where the gas prices are so extremely high (averaged $3.45 per gallon over the year, or $0.32 per mile [ouch!!!])
It also didn't help that Big Blue averaged only 10.8 MPG this year (12.8 was the previous norm). Three things killed our MPG - 1) The big 31" tires, 2) way too overweight, and 3) lots and lots of mountainous dirt road miles traveled.
In the nine years I've been in Big Blue I have put just over 84,000 miles on it ($21,939 in gas). The odo now reads 163,000 miles and is still ticking away.
