Purchased to start both airlockers, emergency tire inflation, beach toy/air mattress inflation and horn. Works amazing and survived 2 months of discharging. Another $100 or so spent to separate the compressor from the tank so the compressor is mounted high up in the engine bay and the tank is behind the gas tank. There was a 1/4" plastic line from the compressor to the tank and from the tank to the tailgate quick connect, plus an underhood aluminum manifold for the purge valve, pressure switch, cabinets, quick connect and air. Have filled up an SUV tire and a car tire so far and it takes 2-3 minutes from flat to 35psi driving a full tank.
