Thank very much.
With the 4.88 gears the V6 has plenty of get-up and go (think toque multiplication of the gears). Unloaded it will probably chirp the tires on asphalt (I don’t know first hand because I don’t drive like that) and will absolutely fry the tires on dirt with traction control off. Additionally, freeway cruising at full weight (gear, full water tank, etc) is totally sufficient IF you consider the HP rating. It will maintain whatever speed you want at the cost of fuel. ~2500rpm @70.
I’m averaging 13.5mph around town, stop and go, almost no freeway driving.
Highway only (gas station to gas station), I’ve gotten 17.5mpg, but average 16mpg. I use cruise control, except for climbing grades, set at 70-75mph. Usually 70mph.
