Ugh. Get a 4x4 pickup truck. If you need to use it for "camping" get a shell for the bed or just tow an RV trailer.
4x2 is simpler and no transfer case or front diff to go bad, but it really depends on where you live and if you plan on going offroad at all. In the snow, offroad, 4x4 can mean the difference from getting stuck to getting there.
For $15k, you can buy quite a bit of truck and if you're going to buy that much truck, might as well go for 4x4, IMHO. If it was $5k worth of truck, I'd say fuck it unless you got your own rack and jacks you can use to drop the front diff and transfer case to work on or replace.
Also depends on where you live and your life situation, anon. Are you a big city incel bugman? Are you a betabux paypiggie for some thot out in the burbs? Are you trailer trash out in rural Flyover? Depending on each scenario, you might want anything from a full SUV to just a dirtbike and a backpack. Or you might just be OK with your ecoboost 'stang.
Trailer trash out in Flyover. I'd get a moped and outfit it with panniers. Where to go is more important than what you got to go around on.
Most people will be fleeing the cities, you know. If you already live out in the country, just keep the stang and get a dirtbike or a moped to supplement it. Moped will be easier to work on, for sure, won't need a floorjack or jack stands for a bike.
