Now since it has been a while since I have looked at new GM vehicles, what are the common problems to look for on these vehicles? Also, what are their strengths?

A few other questions. Is there a way to rig up the fog lights to where they will turn on whenever I want them too? Also, where is the rear locker at on this truck? On my current vehicle I have a rear diff lock button to push. Also, does the rear diff lock only work in 4 lo? If so, how do you mod it to where it will also work in 2 hi or 4 hi?

Back in December, I sold my 97' GMC Sierra K1500 4x4 extended cab. I was the 2nd owner of it and it was well maintained. I bought it in 2004 with 98k on it and sold it with 153k on it. It was a good truck but little things kept breaking on it. Mainly the inner door handle pieces and the oil cooler lines constantly leaked. Didn't matter how often they were replaced, they would only last 3-6 months and then leak again. With my family, they are all GM people so I grew up with the full size trucks and Camaro's but I am worried about longevity or re-occurring problems. So if you all could please help educate me, it would be much appreciated!
