I just picked up a lightly used compressor (LR015303) on eBay for $1.25. Really, the word "compressor" was misspelled in the title so no one saw it or bid on it. Anyway, I really don't need one YET but it makes sense to have a back up since I plan on keeping the truck for the long haul. I was wondering if anyone on this forum has replaced the unit themself and if so, how they would rate the job?
