Just traded in my F350 that had the Airlift 5000 and bought a new Ram3500 I installed the bags myself (about 1.5 hours easy to do) however this time I bought the Airlift 7500, for an extra $60 I recommend those they require less pressure thus a little softer ride.
As for airing up, on board compressor is a WAST of $$$, I bought a Hand Held Ryobi air compressor it take 10 seconds to pump up to max. This thing is also capable of filling your 5er tires above 100psi so nice small gadget to have for other thing like rafts and floats also.
Note: I also have a Vi Air compressor however it is a pain to get out and connect just for air bags.
