Not that I want to do it, but I need to drill a hole in the roof of my Elkridge 37BAR. Will be installing a Weboost and I want to put the booster near the bar TV and power outlet. I plan to start from the inside and drill up, does anyone know the distance from the interior ceiling to the roof? I am hoping I can reach it with a 3/4" paddle bit. Thank you for any information.
