A radio frequency identification transponder includes a power supply and a dynamic memory array that stores data. The user is then permitted to log into the communications server if the user is successfully authenticated. An engine is positioned adjacent to the forward wheel assembly and attached to two chassis frame rails such that, at most, only ten percent of an overall engine height extends above a top of the chassis frame rails. The control system can direct heat to the damper if the damper becomes frozen. The vortex device may then collect a leak flow issuing from the underwater leak.
