Actually, drilling thru the roof to tie-in a rack to the underlying OEM structure is not unusual... and very strong/secure. ARB racks already do this for Jeep Wranglers and Rhino-Rack's own awesome Backbone system for the Jeep also requires drilling (a total of 12 holes) thru the roof.I don’t know what’s more surprising…the fact that it was designed such that you are required to drill through the top….or that there are actually some people willing to do that
