Not sure yet what caused it. All of my lipos were in an ammo box, so it wasn't that. I was just driving along and saw fire. Luckily I had an extinguisher in the cab of the pickup. I bruised a bone in my foot, really badly, tripping over the trailer tongue while trying to get to the trailer door. Most of my stuff was in the back part of the trailer and I think it all survived. I had my E5, E7, N5c, at least $1k worth of parts, and a brand new Honda generator in there. If I wouldn't have seen the flames when I did, it would have definitely burned to the ground and probably burned the truck, as well.
