Anybody towing with a GM hybrid?

I'm looking at options to replace my truck, and came across an 09 Sierra hybrid (6.0L) that looks interesting. Anyone towing with one of these, or the SUV equivalent?

I know many of you will probably want to convince me to buy a diesel. I've owned two diesels in the past, and I know they tow better. This is a daily driver and weekend boat / bike hauler, so for my applications I prefer half-tons.

I'm also considering the regular GM half tons, and Tundra Crewmax. Ford isn't out of the picture either, but I've had great luck with GM vehicles over the years and happy to buy another.

Also, the truck I'm considering has the high end LCD display stereo, but no backup camera. My wife's Tahoe has one, and it is an amazing feature for hooking up a trailer. Any idea how / where it could be tapped in? I think the Avalanches have them in the tailgate handle bezel.
