Class A with a Salvage title

I've never heard of a salvage title based on a failed transmission. I don't own a huge class A, so I could be off base, but I don't think so. As stated, salvage titles are usually associated with a collision or flood damage....something an insurance company would insure. Also, don't you think it is a gall suspicious that is all the ad says? Not much information there. They don't even say "the salvage title is because..." They just say the problem is the transmission. Might not even be related to the salvage title. I say run like the wind.
