But Keystone does not make the electronics. The protection comes from the converter supplier, like IOTA. Compare your converter providers in the rigs that failed. I'll bet they are the same as some of the other units that did NOT fail.
Have the CG write you a letter on what happened, that the CG blames Keystone for faulty parts and what the CG did to cause these Keystone RVs to blow them up like that and Keystone should be liable. I'll bet they don't do that.
But I do like Stiles' idea.
