I'm a big proponent of old coleman camping equipment because of the low weight (

) and small footprint. The stoves and lanterns are very efficient with fuel and can run on gasoline in a pinch, which means if you're out of fuel to cook food, you've got bigger problems

(coleman stoves can't run on diesel

) A properly working coleman stove isn't the fastest to boil water, but it gets hot enough that I couldn't imagine needing more heat. It singes the sides of the drawer it lives in when on full bore with a big pot on top.
Last tidbit about old coleman, if you have any issues with a stove or lantern, they're field-serviceable. I had a problem with my stove this past week where it wouldn't build pressure. Allen's buddy Dale came over and showed us how to take the pump apart with nothing more than a pair of pliers and that we could use a few drips of engine oil off the dipstick to lube up the leather. Worked like a charm and used it for the rest of the week! If one of those butane stoves breaks because it's bouncing around in the truck, (although I have no experience with them) you'd be hard-pressed to break it.
A two burner stove is perfect for two people and (I would think) a three burner would be ideal for a family of four. A cast iron skillet, a cast iron dutch oven and a small aluminum skillet all ride in the truck 100% of the time and a middle compartment in my drawer is reserved for utensils, spices and a few other small things. I don't have a camping table so I use my tailgate as a prep surface and bench to sit on, camping chairs as overflow. That sherpa table looks nice, but I don't see the benefits of that over storage drawers and a tailgate inside the truck. Seems extraneous to me. Storage drawers in the truck can be made more space efficient by running them without slides.
IMHO having a fridge for overlanding is over and above more important than having a table. If you've got means to cook food, it sucks to only be able to bring cooked food with you in the cooler. After a way to cook food, the 12v fridge should be the next purchase.
