Did you use a mod to fix the inventory problems?
Btw, hey, it's me, one of the weirdos who likes inventory management. I never had much of a problem with it in FO4 that I remember, because I just went back to base after exploring a location. Fast travel and all that. "Breaking down" your junk makes it weigh less. Plus, I was constantly using junk to build new stuff in my bases!
I absolutely loved the base building in that game. Pro tip: create a supply route between bases. My first playthrough, I made every location self sufficient. That was a bit of a waste of time.
Now that I think about it, I was a strength/Melee build. That helps a lot with carry weight. Power armor helps even more, although it was a little clunky inside enclosed places.
