Angled tire carrier. Boom. $2500 out the door in one go.
My 5 tires and wheels were $1700 mounted, balanced and shipped, and they weren't even expensive. Like $80 per wheel and $150 per tire. Very modest. Lift was another grand or so though there certainly are ways to do it on a budget depending on your goals.
Or a winch. I just got a $450 Smittybilt this december. Then a $300 synth line for it, plus another $300 for a fairlead, shackles and a snatchblock. And a $250 AGM battery. Can't forget the $350 high output alternator. Or the $500 bumper needed for it, which cost another $400 to have welded and powder coated.

Money goes VERY quickly with 4x4. Buy whatever accessories you want if you have some excess funds. Otherwise I HIGHLY recommend keeping it aside for a rainy day and fixing whatever comes up. I mean, if you're dead set on replacing shit eventually, might as well have some fun with what you got, right? Very little good comes out of screwing with what isn't screwing with you. Just my 2 cents
