Inventory & Disappearing item?

[❃ Galiäna Krüger ❃]

Are there legit place to store item?

Because I had to look up online and looks like only can be store in any kind of storage but then I noticed item often disappear on their own when loading saves. I had just cleared the southern corner village occupied by Legionnaire and with everything on me I had about 485/220 and I put some in a storage then teleport to trade - I made mistake so I reload save and come back to the storage and found I have 200 lbs of worth of weapons, armors and munitions just poof and only food and scraps left.

Most storage items in this game can't be used for personal storage as it won't save what you put in there, as you found out the hard way.
If you plan to use one to store items like that so you can run to a store and back, save the game "before" you put anything in it.
Though just dumping them on the ground is also an option, and sometimes the safer one.
The rest of the time, stop overloading yourself with stuff. Stop, go sell what you have and then come back. The loot you haven't grabbed yet isn't going anywhere.

There are very few places you can store stuff free of any worry it will go anywhere. The nearest one is half way up the eastern side of the map in Novac. You can rent a room there (though they only ask you to pay once).
The other one is in New Vegas and is a little hard to miss if you're following the story.

If you have a bunch of stuff you want to hold onto but don't have a major need or use for, outside one store/location in each town is a "mojave express dropbox". You can cram them full of all of these such items and mail them to a new location where they will sit until you come to pick them up. Acting as a sort of free storage (so long as you remember where you sent them).

Before then though one easy way to be able to carry more is to pick up a follower or two. The first one you ever meet was back in Prim. It's the round robot with all the antenas on the desk of the mojave express.
Interacting with them you can get the option to access their inventory and then fill it full of stuff (to a limit, like with yourself).

The major problem is I like to collect armors and clothing, and weapons I haven't seen before and need at least a copy of it (and if find better quality I sell old one).

I know at the moment safe seems like a good option for me I haven't lost anything I store in it but any other storage in game it just seems like disappearing craps

Most containers DON'T actually respawn their contents. This page lists under "unsafe containers" all the containers that you shouldn't use:

https://fallout.fandom.com/wiki/Fallout:_New_Vegas_containers_and_storage

This page only lists your traditional storage items like lockers or chests, its unwise to store items in dead bodies or any containers that can easily be reached by an npc because they can grab items in them.

Use this mod: https://www.nexusmods.com/newvegas/mods/66832

It will give you a notice at the bottom of the menus to every container if it's unsafe or not. Alternatively, lstewieal's tweaks has a function you can set that does the same thing.
