Personally, which is personal, I'd like the on-board compressor for two reasons. To adjust the ride while...riding. And for leveling porpoises. Yes I know. In the meantime I use my tank of CO2 to air up the bags after airing down to off-road. Same as the tires. A bike pump is...too much work for an aging fellow, and I ran out of money for an on-board. Yet for the price of labor I'd certainly install the compressor myself. There, it had to be said, thank you. Also personally, I like AM's. I have Sundowners and PM's confuse me. Wait...what?
