The auto makers under-rate the written towing capacity of vehicles because of people like you and me. So it will tow just fine, that is as long as you are correct in assuming the total weight is 10,000lbs, and the trailer can carry the 10,000lbs. Id be planning on a slow and steady road trip.
With that said, stopping WILL be a thing that needs to be considered. The trailer breaks are real nice to have, but I would upgrade the Avalanche's brakes for sure. $200-$400 for drilled/slotted rotors and Kevlar pads is well worth the money for the extra stopping power. Relying on trailer brakes to stop the 10,000lb load is scary to me. Everything that you upgrade will raise the towing capacity in some form.
I have a 2005 Toyota Tundra Double cab that is rated at 6800lbs, but tows my 7500lbs without a problem. I have a 24' enclosed trailer with brakes that I tow my mini in. Tundra has 2600lb slam-bags in the back and traction bars. Front has slotted rotors, Kevlar pads, Fab-Tech adjustable coilovers, Truck has 9" lift, and is on 20" rims with 37" tires. Its got .456 gears. Just to get the details out there. It tows real nice on the flats, and does well with slight inclines. But the big-ass hills that we have out here slow me down to 55mph. But that's the legal towing speed in California anyway.
