Completely agree with this thread and speed.....except for the radar part. Is this like getting a free pass to go faster than the posted max?? Or give you a heads-up that a Bear is gonna stop you if you don't slow down? Don't have a radar, don't need a radar. IF I'm going over the posted speed and I get stopped and ticketed, it's my own fault.
Drivers who are "perfect" and never make human mistakes or demonstrate momentary lapes of attention while driving probably will not find the radar necessary. For the rest of us RVers who are less than "perfect drivers" at all times, the radar is just an alarm device to assist a driver to drive safer. One speeding ticket will pay for one good radar device, keep your insurance rates lower and help you avoid going to driver school and keep points off your drivers license. But, this is america and everyone gets make their own choices:):):)
