Hello everyone, new on here! Just picked myself up a beautiful 1 owner 2013 GMC Sierra 1500 in pretty decent condition. The only thing that bothers me, is that it is completely stock, lol. Plan to fix that up real quick. Already in search of some parts to start my DIY project with, I'm not completely new to the truck modifications, helped my brother to customize his Tundra, almost 3 years ago. I've already checked the prices on parts offered in the local body shop and decided that I would rather buy online. Came across WeatherTech, Buschwacker and Bully Automotive websites, that seem to be reliable. Does anyone have any other suggestions? Hope to pick up everyone's advice. Promise to throw up some pictures soon.
