There is one more thing. For the past 3 trips I haven't been able to tune the main tv in to any channels. I didn't think much of it since we were in the middle if nowhere. Well today during my clean up I tried again at home. When we first brought the unit home I could pick up about 20 channels in my front yard. Today I couldn't get any. I had the power booster on, and I rotated the antenna in all 4 cardnal directions And could tune squat. The rear tv picked up a few, but not as many as it did before. Anyone else experience this? I have an apointment @ the dealers on the 19th, maybe I'll mention that to them.
