Here are photos of my BBQ storage. Newer models with larger black tanks, and electrical in this space may not be able to make it work. It is a great out of the way spot for when not in use.
Here it is in place with the cover on, Still lots of room around it to store other things.
With the cover off. It needs a good cleaning. We cooked lots of aphids on the outside in one campground near Zion Canyon last fall.
Here are the cleats that keep it from moving about. Note I also had to angle back the support brackets. And yes, I know, I need to use that vacuum on the left to clean up the crud.
As a bonus, you get a wee glimpse of my floor. More to come in a later thread.
