Replying to 4x2 truck in snow

Aight, so I got a 03 4x2 ford ranger this year for a really good deal.  I just bought and installed a canopy from the dump that cost my 25 bucks.  I know that 4x2's suck cock in snow, but I want to be able to use it for car camping and shit.  Plus it gets really good gas millage, 29mpg highway.  With chains and my mud tires do you think I should be able to drive it up my mountain on a heavy snow day? Or do you think im going to kill myself?
