I got the tank on the driver side. I did some reading on truck tanks this evening, I guess it's 20 gallons?

However, if it is in fact a 20 gallon my gauge is way off because it's reading just about empty when I could actually have almost 1/2 tank left. Maybe I'll siphon out the remainder when it gets low to see how much is left.

In addition to a cam change, I have to think an OD trans in this situation will really help my highway mileage situation. A 20% drop in highway rpm over 50 miles has to make a pretty good dent.

I can't justify driving this thing on a semi-regular basis, I'll spend more on gas in 6 months than I paid for the truck. I've driven it about 1,200 miles so far @ 9.3 mpg...

Looking into getting an A/F gauge before I make any major changes. I got one in my Duster, it's a nice tool to have.
