As a side note, not only is it more convenient to set up all your crafting in a mobile base than a static one currently - the fact is you generally don’t even want to install most of the real crafting stations, as they take up far more room than you need to.
It’s much more compact to make a bunch of rechargeable tools and toss them all in a single cargo space with a recharging station. All the crafting tools you need take up fairly negligible space, and leave you several more free spaces in your vehicle for storage.
So all of those stoves, foodco buddies, reloading stations and what have you - are basically irrelevant.
More realistically, they should provide considerably better crafting values/times/successes than the hand tools alone do. Then there should probably be yet another higher tier which can only be built as furniture - functionally immobile.
So for crafting you’d basically need more quality tiers for all the tool types, and higher tier equipment would require (or at least benefit from) some of the higher tier workspaces:
1 - Crude stone tools (fire pit)
2 - Makeshift tools (brazier)
3 - Proper crafted tools (highest tier for carryable/rechargable items) (survivor mess kit)
4 - Vehicular Workstations (RV Stove)
5 - Full Workbenches (immobile) (Kitchen Stove)
The game obviously already supports this idea pretty well in terms of the available stats - it would mostly be a somewhat extensive rework of the object data to make it actually happen if people thought it was worth it.
