Why, yes. Yes I have. And it turned out stupid ugly and not able to handle highway speeds. I saw what I did wrong as I looked at canvas covers done right, military cargo truck and trailer covers. You may be able to get one to fit your truck from a surplus dealer on that auction site or elsewhere. But a like-new cover and the associated bows and other hardware will not be cheap. Best option these days is a tent made for truck beds. They aren't cheap either, but don't look crazy stupid ugly. But they do have to be removed for driving.
Here is one that you can drive with that I hadn't seen before. But it is $500.
