I'm trying to get some ideas for mods for my 2000 blazer ls. I will be doing lots of highway driving with mild off roading on weekends and lots of driving in the snow. My plan was to put 31 inch mud terrain tires on it not sure about what specific tire yet. I've also read a bit about lockers and have thought about getting one. Would front or back be better? would it make my truck less reliable? I'd like to get some other ideas for mods as well
