And my ONE concession for getting a newer vehicle, even if it's smaller, is that I MUST sit up high, like I do in my Expedition. Of course, big and cumbersome is relative. My SUV is a lot smaller than the 1960-something grain truck that I learned to drive in, and back up (using only side mirrors) with precision, to offload the grain.
And I try not to feel too guilty about the gas mileage. 'Tis the oil business that kept me fed, clothed, and a roof over my head growing up - and continues to do so for a large portion of my family. ;)
A yearly "road trip" for us, though involves 2,000 miles one way, so 4,000 miles round trip. Us, our pets, and all of our luggage and various needed supplies - and we still barely fit. And I pack light!!
