Many years ago I had a Chevy Astro AWD extended van. It was great for towing (within its weight limits). I prefer AWD for 99% of road conditions over 4wd. 4wd doesn't really excel until you get off road and even then a good limited slip differential or locker makes a huge difference.
I wish I had an unlockable center differential in the transfer case of my pickup for snow and ice conditions!
