FROM THE DRIVER SEAT
Cutting into a perfectly good, brand-new truck isn't for the faint of heart; however, with the proper tools and some skill, this install isn't going to take you all weekend long. A full day, from start to finish, is the average install time (with a buddy to help support and lift), and Webasto includes good directions to make measuring, cutting, and wiring as explained as possible. The owner of this '09 GMC Denali loves the Webasto Hollandia TVS 900 ST sunroof and uses it on a daily basis. Up front, the large wind deflector brings in fresh air and doesn't do it with a lot of wind noise. Getting into the truck and looking up, you'd never know the sunroof wasn't a factory piece and without all the other extras, the owner saved thousands of dollars.
