Do you happen to remember the size and where you purchased it? I have a 2 burner gas stove in my Jayco. The knobs stick up about 2". A tray is a great idea. My TT is in storage so not easily accessible to measure.
My DW bought a wooden cutting board cover made by Camco. What's good about it is that it has rubber feet that are slotted to fit the stove grate. No sliding around and we can leave it on while traveling
