I don't have access to Horizons beta so am wondering how many internal slots are needed for planetary landing. I assume these need to be taken from existing ones and aren't new extras, so you lose some current cargo or other modules to accommodate them.
All ships get an extra dedicated slot for planetary landing module. On top of this, to fit an srv in, you need to buy a vehicle hangar, it's minimum 4t.
So you need to dedicate one internal slot to the srv(s).
