I live on an island now with a driveway that has 15-20 degree slope. It snows rarely, but garage is insulated and I need to get a heater near the water pipes. It snowed the one day I had to get to the ferry at 650am for jury duty. I'm glad I had the TRD - it wasn't much but waking up to - doo-dee-doo - drive to ferry and unexpected 2" of snow...causes some anxeity.
