Brian, We use FMTV and are very satisfied. You have to understand that the unit is little more than an electric compass. Once you make your initial adjustment it maintains that compass heading. It makes no elevation adjustment so if you are rolling the TV won't work. You need to make adjustments in the elevation angle of the dish about every 100 miles north or south because the satellite angle will have changed. Once you do it a couple of times it becomes second nature and just takes a minute. We have a number of Krogen friends who also have them and seem to be pleased. We are believers. If you have further questions feel free to contact me. Regards, Randy Pickelmann MORNING STAR Clearwater, FL
