One of the things that I discovered from using the grill in the new position.
When I was just dragging the grill out of the garage, using it, and putting it back, I had it by my kitchen door. This is one of the places I am considering as a permanent location - although it is around the corner from the garden (so away from the "social area"), being next to the kitchen has a certain convenience, especially when doing winter cooks.
The preferred location is where I have put it now, which is by my garage (convenient for power), and actually in the garden.
However, I have discovered that in this position, my Maverick ET73 no longer reaches into my lounge, which is a bit of a blow. Perversely, the el-cheapo "Grill Alert" device I bought before I got my Maverick works absolutely fine.
So that is another thing to consider. I understand that the latest Mavericks have a longer range, but it is an expensive gamble.
