I used to hunt out of a Grand Marquis. A deer would fit in the trunk but preferred using a hitch rack. I have a '16 Kia Sorrento now with a 4 banger and I'm totally sold on that size of vehicle. For weekend trips it's so nice to pull over anywhere and sleep in the back. It's a little snug with gear but if packing efficiently it's fine and saved a ton on hotels and the hassle of tent camping.
Didn't read the entire thread, maybe this was mentioned already about gas mileage, but it's a different way to look at the savings
Get a more accurate picture of fuel savings by measuring efficiency in "gallons per 100 miles" rather than with the current "miles per gallon" system.
