if it rides like crap, then it was done wrong. if it leaks, then it was done wrong.
all of the members in my club have their trucks bagged, plus i know a ton of other people with bagged trucks. some ride like caddys, and some dont. some have leaks, some don't.
an air ride setup is something you don't want to cheap out on, you will have a ton of problems if you get cheap parts (aim industries) you also have to keep everything maintained, especially the compressor.
