H2 On Board Compressor

[ICEMAN]

Does anyone here know if the on board compressor is stronger than a aftermarket one?

Local dealership tie-monkey told me that the on board compressor is the strongest in it's class for the H2.

I asked about the aftermarket one sold in the H2 accessories catalog and he said that the on-board on is better and is rated to pump up the H2 tires..the aftermarket one won't fill up the H2 tires..

Is he just blowing smoke?

Thanks
