Suburban Maintenance 1500 vs 2500

One of the best things about that period of 2500 is the braking system. I had an '04 2500, and I was still on the original brakes when I traded it at 140k miles. I discussed it with the GM parts guys, and they said they were seeing 2500s come in with more than 200k on the brakes. They said to just flush the brake fluid every 50k, and you shouldn't have to worry about brakes for a long time.

As for other maintenance, it was pretty much a wash between that one, and my 02 1500.

If the 2500 has the 4L80/85 transmission vs the 4L60/65 that would be a plus. Like Donn states the less you max out a machine the better to a point in my view.

The biggest expense difference is probably tires. You can buy some pretty cheap "P" metric tires. Whereas a decent LT tire will cost you more money. Get a 2500 and go happy in the knowledge that you are not going to be maxed out with just passengers.
