Hey Danny. I went and pulled the Curt RVi Series Shadow 2 Flat Tow Brake System item # RVI94FR from the warehouse and took some measurements. The Boost box measures 6" long x 5-1/2" wide x 2-3/4" tall. The Shadow 2 box which measures 4" long x 5-1/4" wide x 1-1/8" tall.

I took a box to simulate the booster box, which was approximately 1/8 inch shorter than 2-3/4 inches high. Upon fully closing the hood before securing the side hook, the box began to crush. I captured photographs, but unfortunately, I am unable to attach them here again. I am uncertain about how others are installing their compotes on the fuse boxes, unless their fuse boxes are of a different height. I have some time before purchasing in about a week or two and may consider the Curt RVi Series 4 Portable Flat Tow Brake System - Wireless Monitor - Proportional, as we are not full-time campers. I just add a Curt RVi Series Towed Battery Charger+ for Flat Towing. I appreciate all the feedback. Danny
