General Comments:

The 195 h/p vortec has been a brute!

The EGR valve acts up every once in a while and check engine light comes on. (fixed by rapping on the thing)

This truck goes through anything!

Tows my boat well.

Very reliable even at almost 200m miles.

Seats still are not worn through yet.

The biggest problem with this truck so far was the aftermarket fuel pumps!

Starts even at 25 below zero!!!

I would not hesitate to buy a new one from GMC, however $30,000 is just too much!!!

Faults:

I have had those EGR valve problems.

The first time I took it to the shop. $200.

Then about 50 miles later it bogged down again.

And I wasn't in a position to turn around and go back to the shop.

So I took it out on the HWY and FLOORED it.

I got it up to about 100 mph and then slowed back down.

Then I took it up to about 85 and slowed back down.

I haven't had any problems with my EGR valve since.

And I saved $200.

I suggest you try to clear out the that valve by acceleration.

It will blow itself out.

If you don't want to fly down the HWY at 100 MPH.

Take off from a complete stop by punching it.

It worked for me and it lasts longer than a service call.

Drive safe.
