I also have Directv and can only see a problem if you park under any shade trees blocking the signal of the satellites(is this a stationary on the roof?) I have a VuCube from CampingWorld for about $500, with 100' of RG-6 cable to move it around to an open south sky. On the menu of the controller is a satellite set up option. Select 18" round(1st one I think), go to satellite strength meter & use the remote controller to find your satellite, locking in your best strength. Only a very few times did it take alittle longer(because the ground setting the VuCube wasn't level), but I've never had a problem and only took a few minutes for set up. I don't go camping to watch television, but if I'm paying for it anyway I might as well watch something(sometimes can't pick up local channels due to the terrain). Good luck in your decision.
