I'm running this battery from Advanced because it's the best I could buy locally that day, in an 03 Silverado 5.3L. I don't think my usage and experience will help your decision though. It's been in about a month and 2000 miles, however I don't have it in any kind of bind, so my opinion is about useless besides for a daily driver with a ton of miles. I'm building my system sort of backwards, because I'm also putting about 1200 miles a week on my truck currently and need the dependability. I replaced battery first on the project with this one, and did a full tune up replacing all the sensors, cleaning the throttle body, etc, and am currently getting into doing the big 3 and getting ready to put in a high output alternator, before I install the amps.
