Sorry for the noob question, new server admin here.

I have backpack installed, works perfectly.  I have installed Player Rankings and have that setup as well.

What I'm after is when the player hits X hours and gains a rank, they get another row in the backpack.

Can someone point me in the right direction?  I can't quite figure that out.

Backpacks currently only supports granting capacity by number of rows, not individual slots. A feature request was recently made to support individual slots but that change is a bit involved to make backwards compatible, and I am pretty busy, so that feature may not be implemented for a while. If anyone wants to get involved and contribute, I can give some pointers.

As for how to grant additional rows per player ranking, I assume each ranking has a separate Oxide group. As such, you can grant permissions like backpacks.use.4 to a specific group to allow players in that group to have 4 rows of capacity.

That is exactly the system i use , i have default+first 2 ranks with 1 row, Then they progress an additional row at a time as they gain rank.  All Ranks should have been created as a group first then  the hours required are setup in Player Rankings, then you set up the permissions, use /o.grant <group> backpacks.use<number> you will get a confirmation message,
