When I went full time I tried them all! And threw them all out or gave them all away!! :C
THIS is what I ended up with. Fits all the needs of grilling. And more importantly takes up very little space and is FLAT top and bottom for storage in our very small RV storage bays.

The thinnest and flattest bbq grill I have found!
Takes up the space of a laptop AND the top is flat. Which means you can put stuff on top of it in storage bay. Weber Q and most of the others have rounded tops and/or handles on top.
They come in all combinations.
2 burners,
1 burner w/grill,
Full grill
.....and pancake type griddle accessory add on for all three.
They are found at big box sporting stores and are made by several different companies. camp chief ranier, texsport, stansport, coleman. Different brand names same stove.
