I have a 2 burner similar to this less expensive one. I got it a long time ago when it was $10 bucks. (now the cheap ones are like $30.) For a wind guard I would make that out of sheet metal with some piano hinge purchased at a liquidation store for cheap. (that stuff can be expensive)
The gas tank input on mine is at the left side which makes it perfect for my cabinet. Mine has a 1/4 inch wire grill on the top and the legs under it are 1/4 inch wire and the fold under the stove and look like a "V" on both ends.
Now on my metal counter I've drilled 4 holes and installed "J" bolts with small coil springs and a retainer nut
at the end so these fastenings are spring loaded. When I'm ready to put it in the Van from outdoors use
I set it up on the counter and reach under the counter pushing up on the J bolts and turning them 90 degrees to where the hook of the "J" fastens down over the 1/4 inch wire leg at the bottom of the "V".
Thus the stove doesn't move when held in this manner. Removing it to take outdoors takes only a few seconds, using the reverse order. If you can't find "J" bolts you could always use small "U" bolts where you cut one side off and make the "U" into a "J" shape.
That's how I handled in for my Van.
