Does anyone have grilling recipes for 7-bone chuck roast?

I have roast that is a little over 9 lbs and I would love to grill it- I know some will agree and some won't but I would like to try. I intend to apply a rub overnight then grill it at a low temp so it will be tender. Because it is so large what temp should I grill it at and what is the estimated amount of cooking time? additional advice is also welcome! thank you!
