I think a lot depends on how close you are to the other three, what you are hunting, and realistic expectations about your odds of success. My brother, two close friends, and I took a 10 hour trip to Wyoming in a crew cab Dodge. The trip there and back was really enjoyable and it wouldn’t have bothered me a bit had it been twice as long. Lots of stories were told. We did have a bed that was about 6.5’, a cap, and a receiver hitch rack carrying a big cooler. We were pretty loaded on our trip home with a moose, and the half ton truck sat a little funny. I think you would be scratching your head if you were after elk and got more than one.
