I had a blazer before my current pickup. Go with the pickup. No questions asked! It is a royal pain in the butt to try to keep the inside of an SUV clean when you're throwing wet decoys, waders, dogs, dead deer, birds for dog training, and other stuff inside your vehicle. I did this for three years, and that was plenty. I'll never be without a pickup again.
