I have the dual tuner in my trailer for over a year and have had no problem. I have towed the trailer over 4,500 miles and trailers are not a smoth ride. Dish is who I use the only problem I have had is when I called to change my local from Phila to NC they changed the zip code on the billing. That ment that I never got Octobers bill so thay called me. When it got fixed they gave me premum move ch for 6 months free for there mix up.
