311 SR-1 Silent Thunder Platform 4 Sale
 

I removed mine and it is available for the right offer, I was thinking around $1000 and it would be best to pick up or meet somewhere in the midwest as I would need to go freight if shipped. It is near perfect with all the hardware included. I cut holes in the bottom with a hole saw that a access hatch will fit into or they could be filled in easily if need be.
