Ive also owned them all, big 3. I have a 05 Z71 avalanche now with the 5.3. 210,000 on it and really only wear parts have had to be replaced, water pump being the biggest deal. Hope I didn't jinx myself writing that.
When the 5.3 goes, new crate motor will take its place. I drive 15 miles a day to and from work, can't justify the cost of a new one for me.
Real good friend of mine works at the GMC dealer. Their new trucks are incredible inside and out. Price is outrageous though.
One of my riding buddies has a 18 250 king ranch, traded in a 14 king ranch. Also incredible inside and out. Old one and the new one, both diesels. Old one he replaced the radiator at 150,000 miles. He mentioned they are plastic or mostly plastic, something to that effect. New one is the same deal.
Dodge makes, or made a Mega-Cab I rode in. Guy had work done to the diesel and dam that thing was fast. Extra room in the cab was real nice.
Vehicles have come so far since I started driving in the late '80s, its crazy. Back then if a vehicle had or near 100,000 miles it was done. Now I'm driving one with double that, crazy.
GM, ford, dodge all make great trucks. Have to hope you get a good one from the manufacturer you buy from. If I was in a position to buy a new truck, I would choice the interior I liked best and the best ride.
