I have the 10,works well.On my older trucks i had the old A/C conversion done by a fella in Commack or E northport,Somewhere on Rt.25.The under hood Quickair3 is nice also.Dont forget the plug kit,the above mentioned ether to reseat the tire,a couple cans of Prestone tire jack and a tall jack.Just a word of advice,Dont try to reseat a tire withether after using an aersol fixaflat.Lets just say Im glad it wasnt a crowded beach.KABOOM
