Are you moving to the town itself, or to an outlying area? It looks like the town is small enough that, so long as you're living and working in town, you'll never actually need to drive, and there are nice side streets and trails to bike on. Isolated small towns often have a driving culture, but you can easily opt out when the whole town is three miles wide at its broadest.
If you're in town, things aren't that different from a neighborhood in a bigger city-- you have a grocery store from which you'll buy your fresh foods, and it looks like there's a dollar store in town too-- figure out what you can get good deals on there, and generally shop around for the best prices in town. If the grocery store is dramatically overpriced on nonperishable items or you need other sorts of goods, it looks like there's a Walmart 80 miles away, so occasionally make trips to stock up on nonperishable stuff, share trips with a neighbor if you can, or use Amazon. But for fresh stuff, it probably doesn't pay to make 160 mile round trips regularly to save $1 a pound or whatever.
Oftentimes in a small town, you'll find used stuff for sale on a bulletin board in a grocery store or coffeeshop, rather than on Craigslist.
You'll have plenty of free outdoor recreation options, and I'm sure there are various mountain biking/hiking/camping/etc. clubs around town you can make friends with. You can probably buy rich people's cast-off outdoor gear cheaply at local thrift stores and on Craigslist, especially at the end of various seasons.
Once you get to know the area, you might well be able to set up a side business doing selling ski tours or mountain bike tours or whatever.
