So for those of you who have followed and contributed to the thread I started on Air Down vs. Not, thanks for your input. Here is the followup -

One of the other reasons I haven't been airing down is that my most common wheeling areas are far from a nice air compressor. My little Wally World $19 air compressor takes all day to air back up one tire (great for emergency, not so great for regular use).

What do you have for on board air? How well do you like it? I am especially interested in those of you who do not have on board air integrated with your winch (Knappster, I love your setup, but I already have a winch). Anyone have a compressor that plugs into the winches power supply but is not part of the winch?
