Tahoe & Suburban The power, space, and brutal towing ability make the Tahoe and its longer sibling, the Suburban, arguably the best full size SUV's on the market today.

2013 Chevrolet Suburban

First problem with Tahoe, but nothing can be done, yet!

Not positive but I don't think the Eaton G80 locker needs the Posi-trak additive. The additive is for the clutches.

Well right now I am happy they did not find a problem, but I am still a little worried it will pop its ugly head when I move back to FL and start towing my boat.

My current boat is 6,000lbs tow weight. Although I will be getting a new one that will weigh 8,000

I hope the stress from towing doesn't screw it up to the point of catastrophic failure.

My last two chevy trucks are almost near 200k and they never had a warranty issue, so I guess I'm overdue to encounter issues on this one
