We were about 2 miles behind the crash. It was hard to tell who was involved. I saw a old lady on the ground with a couple people around her and the guy and girl around their dog on about 30 feet away from the old lady. I was looking for a second car but never saw anything. The lifted "Brand New" chevy truck looked like it had rolled over and the trailer with the sandrail in it was totaled. It was hard to tell but the sandrail looked ok. The truck broke the pass side front wheel off and was laying under the a-arm. Looked like a real mess.
