My sports cars are black and LOVE the look of black cars, for something fancy that I was proud of I wouldn't pick any other color. But I've had a black truck that I actually used like a truck and it was awful. Swirl marks from driving a street car with a little bit of sand in the breeze or washing it too hard shows in black paint, needs to be buffed/polished regularly to keep it looking nice. Using it like a truck even lightly just DESTROYS the finish.
If it's gonna be a beater truck for hunting you might as well just leave it whatever color it is, or paint the whole thing flat black if you feel so inclined. Also I don't see any truck in your sig so I have no frame of reference, but unless the thing is whooped I'd leave it alone. You say you can't afford new bumpers, but unless they're rusted to sh!t and banged up real bad up (like you're thinking of putting bondo on them) I can guarantee it will look better however it is now than with some peeling flat black spray painted over it. IME it's damn hard to get paint to stick to chrome even if you scuff it up.
I've bought a couple vehicles where someone painted the chrome trim black and it looked freaking awful both times. Took most of it off with a pressure washer because it was already starting to fall off, and then I was just left with cloudy scuffed up chrome with little black bits of paint left behind in the creases.
Especially the door handles and mirrors, any paint there wouldn't stay decent looking for a month I bet. Some scratches and dings in chrome doesn't look the best, but it looks a heck of a lot better than someone who shot black paint over said chrome. If you could find someone selling black plastic trim it might look cool, but just slapping paint over the chrome will not look nearly as good as you imagine, I promise. Blacking out the grille and wheels looks decent sometimes, but that's about it as far as see it. The 89-91 Burbs and Blazers and Crew Cabs bad black side trim, but it was a totally different style and in my opinion it didn't ever look too great even when fairlynew. These trucks were designed with chrome trim in mind, that's why black still just isn't an option even aftermarket.
Do whatever makes you happy, but from my own personal experience I would have to say don't do it.
