Just went through this whole thread from start to finish... you guys have done some impressive work! I picked up a 2015 Yukon XL at the end of June because we just had twins and my Mazda CX-9 wasn't going to cut it. I got the SLE so that I could have the extra seat in the front, but I've been pleasantly surprised with the level of amenities in this "base model" truck.
Money is tight, but I'd like to try some of the mods I've seen here... probably the LED fogs/reverse/plate bulbs first. Thinking about trying to plastidip the stock 18" rims too. Might help camouflage the tiny rim! For a non-DIY guy is that a task I could reasonably take on myself? Are there shops that will do plastidip for me? I'm in SoCal, so if they DO exist, I'm sure there's one nearby.
Thanks for all the inspiration guys, look forward to seeing more mods.
