Install is pretty easy, but you do need a few tools and supplies before you get started. Obviously you need the "FanTastic Vent U1500 Ultra Breeze Vent Cover", for a Tiffin you will need self leveling Silicon Caulk (different brand RV's use different sealants) and alcohol to clean the area for the caulk. For tools you will need paper towels, caulk gun, power screwdriver w/bits (1/4 and phillips in my case), razor knife and a marker.
