Hello all, New member with a 2012 Tahoe. I've had it for a about 8 months now. I use this to haul the family and my atv's. I made the mistake I'm sure thousands have made and didn't quite have the foresight I needed when purchased. Assumptions were made with my satisfaction with current toys and also the towing ability of Hector in case I wanted more / bigger toys. You know where this is going... I can say with full certainty I now know more than I ever thought I would about GM RPO codes and what I need to look for in pictures to ensure the towing is where I need it in case I replace Hector (of which I'm considering) with another from the GM stable of barges. There are definitely some quirks and features of the ol' chap, the highlight of which being it was already lowered when I purchased it (something I've said I'd NEVER do; purchase a pre-lowered rig). Boy, does it ride ROUGH. I absolutely love how it doesn't wallow in corners though. I'm fine with it being lowered but would love to lessen the harshness of it. I have no idea how much it's lowered or how to address replacing ANY of these components if they need it. I'd be fine trying just new shock/strut but I'm confident there is more to it than that. Regardless, I'm here to learn. Even if I get rid of Hector, I'll still be in the right place for knowledge of his replacement. I'm also in the market for new tires, as the fronts have a habit of going flat in a few days. Could be the tires (the sidewalls appear fairly old), could be the wheels (factory GM 20"). Either way, I'm trying to figure out if some AT 275/55/20's will work/not rub. If I ever bite the bullet on an enclosed trailer/SxS I'll need to seriously consider a lot more than just if the tires rub. But, at that point, I'll likely be replacing with something with the HD Trailering package...which is nice of GM to keep separate than the Tow package...again...RPO codes. For a while I considered biting the bullet and replacing all the hardware...bought a MaxCool 4k external trans cooler (or whatever it's called, it's been in the garage for months lol), Tekonsha P3 brake controller...then did a TON of research which lead me to just replace the damn thing if needed. *sad trombone Anyway, I ramble. So I'll stop now. Look forward to learning. I doubt I'll have much to offer, as this platform doesn't have many secrets anymore, but hey...never know. I do have the RPO list (2 of them, one of them is good...) so you know...got that going for me. I'll figure out how to post a pic of Hector too, eventually. Take care!
