I have a new GFCV2RTT currently on my 5th gen and it works great, interested in moving it to my 93 80. wondering if anyone can give me their experience with one installed on their 80 with factory GFC 80 mounts. ? is the wieght added to the roof noticible in a negitive way. did it effect MPG? just anything you can think of on how well or not it works for you. please only people that have one or know a friend with experience. just throwing out opinions without having one is not what I am looking for.. I understand CG and areo dynamics just looking for people that have reall world exeprence with this RTT 80 combo. thanks
