Ok, I don't mean to nitpick but there is a huge difference between a bbq pit and a GRILL! Steaks, burgers, or chicken cooked on a grill is NOT bbq. Bbq=slow and low Grilled=hot and fast
Ok so the rant is over, this is what I did:
I had a few legs to some rolling walkers (like old people use) laying around so I mounted those vertically on the outside of my rail.
Then I bent some 3/4" electrical conduit out, right, right and down again.
Then I attached a piece of painted plywood to the conduit, and I attached some 1/2" pvc around the perimeter of the plywood to act as a rail.
This gives me a multi-use platform for grilling or whatever.
Here is a picture of me grilling some steaks last year. I have since made the table wider to accommodate the propane tank a little better.
