I just searched for this not too long ago. I seen people were saying they were using 1/2 and 3/4 gap but they were worried about flex and the bed hitting the cab. Don't know if they're vehicle were trailer queens or not. I also seen others that were daily drivers saying 1 1/2 to 2 inch on the gap. I never could find anywhere that said what the factory spec was. Post back up if you find that out I'd be curious to know...
