I started off with my 2000 K2500 GMT 400 that had a 6" lift with 35's and tons of mods, but as it aged and was unable to fit inside anywhere I had to make the toughest call ever of putting it up for sale. Luckily one day I got a hit on craigslist asking if I wanted to trade for a 2005 1500 ext cab. It turns out he babied this truck and it even still had original window sticker. This truck fit my needs with the 4 doors and only slightly lifted stance. Either way I knew it was a solid truck and knew my truck was going to a good home so I took it. When I got it, it had pretty worn M/T tires on it and a dual exhaust. Eventually the one side of the exhaust came down so I replaced it with a single out MBRP exhaust and some General grabber A/T tires that I got a steal on between a sale and rebates. Other things I have done are fix the cluster so all my lights and gauges work, replace the 2 front impact sensors that went out and some new brake pads. Overall I love this truck with the 5.3, its a nice combo of power and fuel economy. I really miss my 400 but I am glad to have this truck to replace it.
