I wonder if the big problems with Directv Customer Service is actually concentrated on forums like this. Maybe it is only a problem for RV type uses. I have both home and commercial services from Directv and never have an issue other than when they are having a fight over content fees and a channel is blacked out or the occasional loss of signal in heavy rain or snow. Both of those cure themselves without intervention of a customer service agent.
It just might be that customers with RVs constitute 2% of their business and 90% of their problems. If that is case, it might be in Directv's interest to actively eliminate that segment of the market.
