I have an older Chevrolet Tahoe...a beast, but I love her. She has the big engine and doesn't get great mileage in town but does well on the road. They are also available in a hybrid version...don't know what kind of mileage that one gets but it might be worth a look. Mine has heated seats,leather, AC, sunroof, Bose stereo and all the luxuries you could ask for. And,like I said, I love her. I also have back problems but it doesn't bother me in this SUV...
