I'm guessing that the further north you get the more 4wd you see....... depending on the annual snowfall amounts. I seem to recall seeing more 2 wheel drive stuff in the southern U.S.. I've been driving nothing but 4wd Tacomas , ( 2 different ones ), since November 1996. Got sick of a 2wd truck in winter, and with annual ritual of getting a couple hundred pounds in the bed over the rear axle to help with traction.
