Ultimate Beds, allows you to change the number of sleeping bags and beds you can place compared to the basic limit imposed by rust.
You can also decide the time within which a sleeping bag/bed becomes available for spawning and adjust the time for successful spawns, all through various permissions, including VIP permissions.

It also allows you to define the distance between the various beds, preventing them from going into cooldown between them.

This plugin uses the permission system. To assign a permission, use oxide.grant <user or group> <name or steam id> <permission>.
To remove a permission, use oxide.revoke <user or group> <name or steam id> <permission>.

• ultimatebeds.default — Assign the limits configured in the group: default.
• ultimatebeds.vip1 — Assign the limits configured in the group: vip1.
• ultimatebeds.vip2 — Assign the limits configured in the group: vip2.
• ultimatebeds.vip3 — Assign the limits configured in the group: vip3.
