Generator shown below is open skid mounted but our units are enclosed in a weather resistant cabinet and are mounted on trailers with an auxiliary fuel tank.
This unit has a 200 gallon tank and at full load this unit uses approximately 15.8 gallon per hour. With a full tank you should get approximately 12 and 1/2 hours of run time. Of course most of the time you are not running at full load and it is possible you could get a much longer run time.
