new GMC 1500 2x4. No one needs 4x4 anyway

This past spring I bought a 2012 Silverado 4x4 to replace our 2005 Avalanche 4x2 for towing, gifting the Av to our older son. However, it's a real handful in the snowy conditions we get here in S Ontario at this time of year, even with additional weight in the back. :M Just yesterday we were out in the country in the Silvy and on our way to our destination I intentionally took a really steep road as this was the first opportunity I've had to see how the truck would handle in these conditions. The truck is equipped with electronic 4x4 which means I can select 4x2 for use on dry surfaces, 4x4 Auto for use on varying surfaces, 4x4 Hi, or 4x4 Lo, just as I used to be able to do with our previous 2006 Silverado 4x4. I have no idea what the slope on this roadway is but it's really steep so I wanted to see if it would negotiate these slippery conditions any better in 4x4 Hi than 4x4 Auto. Using Manual I slipped it into 2nd and alternated between the two settings - surprising to me but 4x4 Auto handled the task just fine, no slipping at all on our way to the top of the hill, so I'm not sure I'd ever have a need to use 4x4 Hi. 4x4 Auto is also much simpler as I can now confidently tell my wife to just use 4x4 Auto anytime the roads aren't bone dry where 4x2 would be sufficient and just ignore 4x4 Hi which GM warns against using on dry roads. Having suffered through many winters with the 4x2 Av I have no interest in ever again owning any truck that's not 4x4.
