    BigRed, if your in Van, and not out in the mountains, 660 will get you through a downtown winter.

    Today's trucks have so many electric "features" that the 800 is considered a "probably never fail in the Yukon" requirement. If your parking it outside this winter, change to synthetic engine oil and you will be fine.

    In fact, if it fails to start, call me I'll drive out and give you a boast (about 4 days), haha.

    Sorry, but if the factory calls for a 800, you should have an 800. The 660 may work for a while, but it won't last nearly as long as the one the factory calls for, and if you do plan on adding any aftermarket equipment that takes extra power, you may as well get the right battery. But, you mentioned a possible second battery, maybe you can keep the one you have and use that as a back up.
