Nashville "RV Bomb?"

This is the best I was able to slow things down with my software. To get any slower I would need footage from a camera that actually recorded it in slow motion. As the fireball dissipates, it shows the origin of the explosion and it is obvious that there was no RV parked there. The only vehicle on the street that looks like an RV is parked across the street from the explosion origin and down the block. This was NOT a bomb inside an RV. I am not positive what it was but I do believe my own eyes, no RV was parked where the explosion originated. This looks staged.
