We have the COLEMAN ROAD TRIP grill and like to always setup at the edge of the patio. was never in favor of having it right next to the trailer side.
We put the large patio rug down first and then setup the coleman grill off to the side of the run - all still under the awning...
I have two of those slat type tables one on each side of the trailer door under the awning... Great catch all area for thing incoming and outgoing from the trailer...

I'm surprised I don't have a good camp setup photo handy... This one is close with the coleman grill behind me when I was taking this photo... At least I got a shot of my good ole CUSINART GRIND AND BREW fresh bean coffee maker haha...
Always have a fan blowing to keep the mosquitoes off of us when sitting outside...
