I think of that day for me, sometimes. It would be a sad day when I have to give up my truck. But, it's paid off, doesn't eat much, and I am a homeowner and motorcycle owner. I have a trailer that has come in real handy.
But, trucks can be rented when needed. A trailer hitch would increase the utility of a car when a trailer is needed. Friends with trucks (or an extra car) can be begged. Life style changes and ways of looking at the world can be altered.
If anything is paid off, that's a plus. If you're still making payments it's simply switching one to the other. An extra vehicle costs in insurance and tax/licensing that adds up when you don't really use it during the year. We keep mine for the heavy snow days and home stuff, but seldom need it. But when somebody needs pulled out or rescued, it's done RIGHT NOW and we all drive away happy.
Personally, I got a small car for cheap that I used for commuting. That was the CRX for $850. It turned out well and we got a new one with even better mileage - the Prius C. I get about 54mpg on average, and that sure beats my 10mpg truck!
Snow tires on extra rims would be a good idea, but deep snow would still stop you. Fortunately, there's no shortage of truck people driving around that will pull you out (like me.) Keep a hook and chain/rope with you for your application and you should be good to go with that.
Good luck on your quest for simplicity.
