The dana 35 gets a bad rep but it can definitely handle more than people think. I used to do scrap metal runs in my truck and it wasn't uncommon to throw 2-3000lbs in the back. Add some NYC potholes into the mix and you've got a recipe for disaster but it never gave me any issues. The comanche is my first car as well so its seen a fair share of clutch dumps and donuts in the snow. It's even got a BA10 trans in it, smooth as butter still.
I strongly agree with this point. On lighter trucks, narrow tires will dig into the snow rather than float on it. Side bonus, better gas mileage. Going from 10.5 Grabbers to 9.5 Duratracs was a game changer.
