I do things along these same lines. I always carry a long gun too. So my daily is old Honda van with a cracked windshield and clearcoat peeling off the hood. I purposely have some "trash" in my vehicle like a burger king bag, an old fleece jacket, an old half tore up bath towel and a pair of my kids boots they can no longer wear that are ratty. I use all of this to cover the rifle. Most that walk by and peek in are going to think "what a pile, nothing of value in there". It's not Sanford and Son level but enough to make people think it's just a poor person's trashy vehicle. And that's the point.In a used fast food bag on the rear floor. No gun stickers of any kind on the car.
