Long haul means I can go into a fight with 1000 grenades and mines all the ammo I want all the food and water I want.. and then after the fight is over come out with everything and I do mean EVERYTHING. Every last power armor every last fission battery every last nuka cola every last spork.
If you're over max going in you'll be
walking have fun in that fire fight..., I mean if you have max weight going into a fight, you probably should have restocked and sold stuff back in town before running in, sure you get to collect ALL of that stuff (even if you're 199/200, but then what? fast travel to town to sell the goodies?...should have done that already...and the cave part still lingers.
Maybe other people don't maintain their inventory but I know I do... and Long Haul still looks worthless.
Edit: I think people are thinking like the "power armor" idea and thinking that they could get 5 sets of it and go sell it, where realistically you'd repair one suit to max and it would be worth far more. and weigh a ton less.
