Smittybilt 2781 Universal Air Compressor

The Smittybilt 2781 is a 5.65 CFM portable compressor with a 150 PSI cap. Larger motor than most portables in its price class, fast enough to inflate 35-inch tires without long duty-cycle waits. Build quality is a step below ARB or Viair (more plastic, basic case), but the airflow-per-dollar math is hard to argue with for occasional trail use.
