Keep as much weight on the back tires as possible. Use lower air pressure in sand and soft dirt. Let someone know where you are going, since 2wd is only half the truck you will need sooner or later. Pull Pal, or other home made type winch anchor in case there are no trees.
Common Sense. It's available anywhere hard lessons are taught, but it costs an arm and a leg to get if you aren't careful, maybe more.
Once you get tired of that, if you can legally do it, convert it over to 4wd, or sell it and get one that is 4wd. It's the only way to fly when you want to venture out of the mall parking lot.
Watch out for 8274 winches on Craigslist or other places. They are an 8K rated winch, but they will pull 9K or more. Cheap is good, but do your research. Older designs are simple and more proven. Some of the new MOSFET stuff is fancy, but can be unreliable, and there isn't much you can do to fix them in the field without a $$$ spare part.
I bought an old Ramsey worm drive for $200 last month, works just fine and will outlast the truck it's going on if I keep it full of grease and don't burn it up from abuse.
