I don't want to have to install a block heater when I go to buy mine... So no SS for me, lol.
Both get better gas mileage than my Blazer, so I'd be happy with either... But there's not many good winter tires for a 20" rim... The 2LT/RS combo has the smaller brakes, so you can run some 18" rims for the winter!
And a block heater is a requirement for -40
Though, at $1.05 a liter (or $3.969 Canadian for a US Gallon) for regular (premium usually runs 10 cents a liter more...)... The V6 will be kinda nice at the pump, lol.
The V6 is a 60 degree V6, right? Smooth running, good power, good mileage...
I miss my old 3.4L TDOHC! lol
