Every tornado interceptor has to have its own anchoring system. The dominators have different types, and a unique spike that penetrates deep into the ground. Every Dominator that was produced by Reed Timmer has two spikes that are not visible outside, but only visible in and under the Dominator itself. Even though this is the first, and weakest tornado interceptor compared to the Dominator 2, and the three, this vehicle has its own unique way of intercepting tornadoes.
Its crazy to think that many famous tornado interceptors used to be completely normal cars with no protection or armor at all. This is what the Dominator 1 started off as.
