I'd like to know too if anyone finds a good source. I got a chance to see the sink and stove units Warfield Offroad had in their sample set up at OX11. Expensive, but I think one of there combo units would be perfect for myTtacoma/Flippac build.
I've got the 2 burner hob and round sink that I installed my current FWC, they are nice. Got them when they were more affordable/available a couple years ago. The 2 burner hobs are available state side again but I haven't seen any sinks/combo units.
I'll be making some calls soon myself I'd like to see about a 9222L combo unit for my build.
Current setup:
