Been down the road with cumbersome kitchens- I like to cook but I value quick camp set-up and breakdown.
Having gone through many setups and chuckboxes, I think I have found what's best for me:

Portable sinks, foot pumps, bulky tables have came & went from my camping gear.
I use the portable kitchen on an extra-large aluminum roll-top table I got from Cabelas. If I am expedition camping, I can just use the kitchen in the back of the truck without the table.
Lid doubles as a sink, lots of my cooking gear (double burner stove with grill & griddle, spices, dry goods, plates, cups, pots/pans/utensils, paper towels, trash bags, etc.) are in there.
May not work for you, but I value efficiency, ease of use, space and my time more than I valued any of the fancy kitchen/sink combos.
