Hi All, I am looking to upgrade from my Trailblazer EXT to something bigger and give the wife it. I have another kid on the way and 2 dogs (large Labradoodles) so with 3 kids the wife and dogs I am thinking a crew cab with a cap will work out. I pull a double axle trailer frequently and have been unable to use it with much of anything in it with the trailblazer and a 20 ft boat. I would like the 6.0L engine, but since the wife is out of work getting ready to take care of the baby I cannot afford new. I came across a really clean 2006 Silverado LT1 Crew Cab 4x4 with a cap. The Truck has the 6L with 97,000 miles on it. In the past i have owned 5 suburban and normally drive them till about 200,000 miles, but I do not know the longevity of the newer style vehicles. Please offer your thoughts on the reliability of this truck as my freind has an extended cab with the same engine and loves it.
