Welcome to the forum Dennis, hope you enjoy your Kodiak.
I think that's due to the lower power output and smaller wheel footprint of the Terrain since that amount into the perfect power delivery and rubber that cuts right through.2011 Dodge Ram 2500 w/Cummins and a 2012 GMC Terrain all-wheel drive. I thought about putting a plow on the Dodge but it would have been hard making turns with it. The Kodiak works great for snow removal.
BTW, the Terrain gets around easier in snow than my truck, well as long as it isn't real deep!
