We have the older one like the picture RoyB posted. We mostly keep the legs folded and use it on the picnic table. We use it for all our cooking. Before a trip I line the water pan with foil and at the end of the trip I take out the foil and throw it away.
I removed the regulator and use a long hose to connect to the low pressure quick connect on my trailer. I think the newer ones have a different regulator setup so it may not be as simple with the new units.
For breakfast I love being able to do toast on the grill side and eggs and sausage on the griddle side.
